Ah, double pebkac. Thanks for the answer and many sorries for the confusion.
My primary language is not english, and i was tired, so the simple "Unseen Text" checkbox (without warning) registered mentally as the opposite.
For the save data, when i tried doing that, i hit "stop app" before attempting to delete which caused it to cancel collecting storage usage stats and just show zeroes across the board.
As for the double menu button though, in the mobile app the menu button simply doesn't exist in the menu screen.
