Asked some folks:

FORT-166226: “Extra buttons do not respond every press when quickly tapping between dedicated weapon and build buttons”

It's better than 8.40, but not completely fixed. Trying to improve it in 8.51. Real fix is planned in 9.00

FORT-168462: “Some extra buttons are not working on mobile”

Aiming a fix for this issue in 8.51.

We use JIRA internally and that is the bug tracking number which we also surface on trello.
