Yacreader stops working...

Hi, I was a happy user of Yacreader on my ipad air2 with ios 13.6.1 and Yacreader library on my macos catalina mac mini, but suddenly the app decided to stop functioning, it doesn’t even open on the ipad... I tried to reinstall the app and restart the tablet, but with no changes... Some advice on the matter? Thanks in advance for your time,

What did you do after reinstalling the app?

I tapped on the icon but the screen turns black for 1 sec and return to the home screen... I don’t know what else to do...

What ios version are you running? Are you sure you uninstalled the app and then downloaded it from the App Store?

Hi, I’m running on ios 13.6.1, I’ve just repeated the process of uninstall + download from app store, but the ruesults are the same... it doesn’t even open... 😥
Since it’s not a device so young anymore, Ihaven’t updated the ios, ‘cause doing it in the past, with other ipads & iphones, it slowed ‘em a lot...

I will try to see if it is something with older versions of iOS, maybe I broke something in the latest update.

Hmmm, it runs fine on iOS 12.5.6...it could be an iOS 13 thing, but it is weird.

I have tested the latest build with iOS 13.7 and works fine for me. I don't really know what's going on
