Could be Improved

I have another complaint. I’m complaining because when I lost pro, there was a thick line of white blocking the bottom of the screen, blocking you from seeing the Pokémon cry and Pokédex voice when you enter a Pokédex entry with a long description. This is frustrating because you also can’t see the names for the Pokémon in the comparator if you scroll down too much. Can you please fix this?

One problem I can find

Lovely ui looks clean but I can’t share my battle team.

Phone overheating and app crashing!!

Hello, I‘ve used MasterDex for as long as I can remember. This app was AMAZING when I got it, I was able to buy infinite teams in the teambuilder for pretty much a dollar, which was epic. However, recently the app is beginning to make my phone very hot when I use it. Along with that, every time I make a save to a team in the teambuilder, the app hesitates before it suddenly crashes, freezing my phone entirely for nearly 30 seconds before returning to normal. This has never happened before and I really want to know why it‘s happening now, it worked perfectly fine barely a month ago and now it‘s just like this. Please give me something at least, like advice or how to fix this.
