Pop out sideloaded app takes long time to load
ChristopherEdling , we got update from engineering team stating that, this is happening because the app never initializes the App SDK (i.e. teams-js). While Teams apps are built on the same web technologies as standard web sites, there are some requirements that they need to meet as documented here:
https://learn.microsoft.com/en-us/microsoftteams/platform/tabs/how-to/tab-requirementsThis is one of the prerequisites which this app has not implemented:
Within your content page, add a reference to Microsoft Teams JavaScript client library using script tags. After your page loads, make a call toapp.initialize(), or else your page isn't displayed.Just wrapping an existing website in an app manifest does not produce a well-functioning Teams Apps. You need to do some additional work to make your websites integrate well with Teams.Thanks,

MicrosoftChristopherEdling - When the app is popped out, it goes through the initialization process again. This process involves loading dependencies, fetching data, and setting up the app's UI. If the app's initialization process is complex or time-consuming, it can contribute to the delay.

- Thanks for your reply.
The app (that I have developed) loads quick when opened in Teams or if i open the about tab and the pops out and switches back to the app tab in the popped out window.
So this must be some problem with Teams.
I will reach out to the other forums and see if I can get an answer there.- I created a new minimal manifest file that loads another simple website and I still get the same behavior with very long loading times.
- I still have not solved this. Can I get any help on this?

ChristopherEdling - As we are unable to repro this issue at our end, could you please share any deployed app, so that we can test at our end and raise bug for this?
I have a small test manifest you can use. All it does is loading a Swedish newspaper (dn.se) in the app.
It loads quick in Teams but if you click the "..." and then "Open app in new window" it opens a new window and it takes long time to load.
