Web page stuck in loading

[Zannaza]

Hey guys and gals,

This is the first time reaching out with an issue I just can't get my head into. So far I used this forums (or google) for whatever I'm stuck with, but just cannot find the solution for the problem I'm currently facing. Let me explain you what's going on and what I noticed.

Let's go backward a few days. I received multiple complaints that several of my Powerapps are taking forever to load. This to a point where it just stops loading, ending up showing just the four amazing loading dots for an eternity. I noticed that 50% of my request either end up being stuck forever, or loading in for as long as a minute. What is even more confusing is that the apps are loading perfectly in Teams, no crazy delays at all! 

The Console is showing the following when it's stuck forever:

DevTools failed to load source map: Could not load content for https://content.powerapps.com/resource/webplayer/hashedresources/HIDDEN/js/player.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

DevTools failed to load source map: Could not load content for https://content.powerapps.com/resource/webplayer/hashedresources/HIDDEN/openSource/oss-phase2.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

player.js:1 AppLoadedEvent Timeout Expired ... Flushing Telemetry

The resource Https://content.powerapps.com/resource/webplayer/hashedresources/HIDDEN/openSource/modified/adal/adaljs.js was preloaded using link preload but not used within a few seconds from the window's load event. Please make sure it has an appropriate `as` value and it is preloaded intentionally.

And this when it does work:

Noticed the request below in my network. This request keeps popping up a few times and either continues loading after a minute or stops after a while, having me stuck on the loading screen.

Who wants to make my day and help me out with this issue? I digged trough the internet with no luck and tried most settings that's being recommended. 

Thank you anyways for spending the time to read this message!

Hi Zannaza,

Hope this gets some visibility as i'm experiencing the same issues, since 2 weeks or so. I have been changing versions, deleting caches, removing connectors/connections and so far nothing is helping. All apps were running fine before. They do work in MS Teams though, that's making me wonder it revolves around authentication. The problem aren't consistent at all, if I start 10 of them, a couple load immediately, and the next time I have completely different results.
