Thank you for elaborating @Croms_Faithful, we’ll be sure to forward this matter to QA.
As you have a data limit, perhaps it would be best to refrain from reinstalling the game for now.
Regarding the saves specifically, you could save them to the cloud in order to ensure they are not lost.
Lastly, do you recall if you’ve used or entered the area of a Battle Standard, as these seem to be behind several issues after the latest update?
