Yeah! All my apps.
Was using the PowerApps on Android directly.
I have cleared the cache but still didn't work.
Installed latest updates; yet it failed to load yesterday.
Tried moving around thinking it could be network reception issues, but that still didn't solve it.
What could be wrong?
Though today, on getting to the office, using the Wifi in the office, it worked but the app was built to work both in online and offline situations, so I'm still worried that it could happen to users.
