[Android] Weird icon change in the payments tab

Issue: intermittently… If you head to:

Payments > Add People and tap that button, don’t click any contacts and just tap back, the “+” icon turns into an orange “A”
By swiping back through the Pay Someone on Monzo list and back to the end (if it’s a long enough list) sends the icon back to a “+”

Details to reproduce: (see issue)
OS: Android 9.0
Device: Pixel 2 XL
App Version: 2.9.0

I still have Android 8 and it does not do this on there so must just be the lastest version that is effected.

Have you tried removing and re-installing the app just to rule that out?

Hmm, mines still the blue + on a 1st gen Pixel, Android 9.
