@ahmed-tarek-salem can you please add in the readme the information how this works

@sallymoc

Done, and I will update that again after moving the endpoint to static qubic

The popup approach might not work for force updates with breaking changes - old code could crash before the popup is shown. For example: backend endpoints removed or changed, API responses in a new format the old code can't parse, or library incompatibilities with newer OS versions. Most apps use a full-screen blocker that runs at app launch, before loading any screens, to ensure the update prompt shows before any potentially broken code executes. If the app crashes when returning from background, that's unavoidable since old code is already in memory - but the next launch will show the update screen.

@ahmed-tarek-salem should we close this PR and only work on the #586 ?

[sallymoc]

@ahmed-tarek-salem I guess we can close this one as it was replaced by #586, correct?

[ahmed-tarek-salem]

Yes. Replaced with #586.
