Before you install
- When Android refuses the install, it is the unknown-sources guard doing it. Grant this app permission in Settings, then confirm the install when the prompt comes back.
- An "incompatible version" message usually means the build was compiled for the older ARMv7 processors that recent phones no longer accept. Look for the ARM64 (ARMv8) build of the same version instead.

Nothing happens when I tap download
Refresh the page and start again — each link is signed for one visit and stops working after that. If it keeps failing, the file is probably being swapped for a newer build; give it a few minutes.
Android says "App not installed"
Usually there is already a copy of the same app on the phone, signed by someone else. Remove that copy first, then install this file — and back up anything you care about inside the app beforehand, because uninstalling wipes it.
