I am a paid user and am using the current version of PowerFTP Pro (v2.0.2) downloaded from the Google Play Store.
On one of my devices (Google Pixel 6) I can no longer use the app as I receive the following message when I load it:
THE INTEGRITY OF THIS APP IS NOT VALID. PLEASE GET IT ON GOOGLE PLAY. THE APP WILL FINISH NOW.
I uninstalled the app and reinstalled a fresh copy from the Play Store in case it had become corrupt but the problem remains.
The app continues to work normally on other devices.
The differentiating factor may be the fact that the Pixel 6 is running the current beta version of Android 16 (Baklava) Build Number: BP22.250221.015 whereas my other devices are on Android 14 or 15.
Any help would be appreciated.
