Note: You may need to make a wipe of the application you are upgrading to this version due to quirk of AndroidX we didn't noticed durring development of this update.
Don't worry, we will publish up an hotfix patch in the coming days.
Edit2: I set it temporary as pre-release until the bug get "fixed" (It's actually Fox2Code editing the post)
