Mission buttons
Every now and then, the recycle, drop, fire (for bursters), and manage (for capsules) buttons will disappear. Force quitting ingress prime and restarting seems to fix it. This happens several times a day to me.
I am on iOS 13.1.3 and ingress build 2.33.1

Manage button has disappeared again.
+1 buttons dissapear and need to close and open ingress to fix it.
Same on Android.
When it happens, keys screen also starts behaving erratically. Only scroll and "Manage" works, but no key could be selected/viewed. To exit from keys screen, you have to press (X) button twice (first touch is animated but ignored).
