Recently, I stumbled by chance over the fact that there isn’t just [Codecov](https://codecov.io/gh/gap-packages/recog) (that’s where the GitHub Codecov integration links me), but also [Codecov](https://app.codecov.io/gh/gap-packages/recog) – which fixes some annoying layout issues (yay), but on the other hand uses different code coverage coloring. Anyway: I was wondering what the relation between the two is? Is this just an alternate view (where is this documented)? Or are the “app.” URLs a preview of an upcoming design? Are both going to stay around? Should I prefer one over the other?! ---

@fingolfin, you guessed right, we are in the middle of a design overhaul. We will eventually move towards only `app.` URLs, so I would stick with those ones. ---

When you say “stick with those ones” I assume you mean “change all your existing links to use those” ? Also, will you add redirects for the old URLs to the new ones, so that legacy links in READMEs, manuals etc. are not broken? ---

@fingolfin, we will be redirecting old URLs to the new ones in order to not break legacy links. I would suggest using the new links going forward, but it should be backwards compatible. ---

Hi, thanks for the clarification! I stumbled on a similar issue (possibly related to the new design overhaul?). When trying to view a file coverage report (line by line view), depending on if I’m from app or the “old” site, I’m presented with 2 differents URLs, and on only one I can see the coverage, for example: Working URL: > **[Code coverage done right.](https://www.codecov.io/gh/mathieugouin/tradesim/src/master/test/test_marker.py)** > > Hosted coverage report highly integrated with GitHub, Bitbucket and GitLab. Awesome pull request comments to enhance your QA. Not working URL (the page loads fine, but the line-by-line report is not displayed): > **[Code coverage done right.](https://codecov.io/gh/mathieugouin/tradesim/tree/master/test/test_marker.py)** > > Hosted coverage report highly integrated with GitHub, Bitbucket and GitLab. Awesome pull request comments to enhance your QA. Thanks again! ---

@mathieugouin, can you give some more details on how you got to those URLs? It seems both are on the `codecov.io` domain ---

@tom Thanks for the reply! Here is how I got both these urls. A. To get to the “non-working” page: 1. When I am logged into codecov, the main page is: `https://codecov.io/gh` 2. Then I click on my repo (tradesim). I am presented this page: `https://app.codecov.io/gh/mathieugouin/tradesim` 3. From the “COVERAGE SUNBURST” graph, I click on “test”, then “test\_marker.py”. 4. I am presented the “non working” page (no line view of coverage data): `https://codecov.io/gh/mathieugouin/tradesim/tree/master/test/test_marker.py` B. To get to the “working” page: 1. Same as steps 1 & 2 in A. 2. From the “Files” list (below the Sunburst graph), I click on “test”, then “test\_marker.py”. 3. I am presented the “working” page: `https://codecov.io/gh/mathieugouin/tradesim/src/master/test/test_marker.py` C. I found another way to get a “non-working” page (it seems related to the fact that the file is from the root vs sub-folder): 1. Same as steps 1 & 2 in A. 2. From the “Files” list (below the Sunburst graph), I click on “finance\_utils.py”. 3. I am presented another “non-working” page: `https://codecov.io/gh/mathieugouin/tradesim/tree/master/finance_utils.py` Hope this helps! Thanks, Mathieu ---

@mathieugouin this is very helpful, and I’ve forwarded to the product team. ---

I’m seeing different complexity numbers for the 2 URLs. Is it a known issue? `https://app.codecov.io/gh/wso2/carbon-apimgt` (INCORRECT) ![image](https://canada1.discourse-cdn.com/flex029/uploads/codecov/original/2X/4/462cb870e3b186f379341bb775984752a7b9e1fe.png) `https://codecov.io/gh/wso2/carbon-apimgt/` (CORRECT) ![image](https://canada1.discourse-cdn.com/flex029/uploads/codecov/original/2X/a/a4fc6360aed6feda62f7a3f7d685ae6f12bc7917.png) ---

Hi @bhathiya, I wanted to try your 2 URLs, and for some reason, the “non-app” URL redirects me to the “app” URL. Could it be related to the browser thinking I’m accessing the page from a mobile/tablet device? However, I’m really from a desktop Chromium. ---

@mathieugouin make sure you don’t drop the last forward slash. otherwise it redirects to the app version. ---

@tom do you have any idea about this? will it be fixed in the app version any sooner? ---

@bhathiya, the product team has been made aware of the issue. I don’t have a timeline for you when this will be fixed yet. ---

@bhathiya we have rolled out a fix for the different complexity numbers issue you were seeing.
