microsoft solitare collection

This recently stopped working on both my iPhone and iPad. I’ve used it for years on both and now it tells me it can’t find my internet connection. I have the latest operating systems on both, and don’t recall the app updating itself recently

I shut down and restarted both devices, removed and reinstalled the app on both, rebooted my internet……nothing works. Other Microsoft games continue to work, using my internet. The game works on my windows laptop.

Is there something to try that I haven’t done already?
