Describe the bug

I have flashed official proxmark3 firmware, Version 3.1.0 on my PM3.
(https://github.com/Proxmark/proxmark3/releases)

I installed AndProx 2.0.4 (95).
(https://play.google.com/store/apps/details?id=au.id.micolous.andprox)

When I start AndProx, the PM3 is recognized.

But I get the error message:
"Proxmark3 firmware update required"
"Please ... reflash to official proxmark.org firmware (v3.1.0/HEAD)"

Expected behaviour

I expected, that AndProx work with my firmware.

Proxmark details (required!)

Is it necessary to flash the version from here???
