Side-bar Controls and Storage Stop Working

[Tifa 0]

Hi,

I've had this issue a few times where the side bars randomly stop working during gameplay and I cannot access my items or create new ones.The only way to get them to work again is by closing the game and losing whatever progress I made that day. 

I'm playing on my Galaxy S10, android version 9.

I appreciate your help!
