Plant glitch in arena PVZ2
Occasionally, in arena mode, the plants get locked. For example, moments ago I selected Tile Turnip to plant in an arena battle, and it planted Draftodil instead, no matter how many times I chose different plants. This has happened to me three times over the last month, with no patterns or similarities between the circumstances (different plant rosters each time) other than the consistent glitch. Closing the app and restarting it seems to work.
I'm playing on an Android tablet, admittedly an older model (2019).
A know issue introduced in the 11.9.1 update where if you pause the game in the middle of the quest or Arena, it stuck with the item you selected with no cool down. I believe this is fixed with the 12.0.1 update once the game is updated.
