Skins for Minecraft

I downloaded this app not too long ago and liked the how the skins looked {dispite the constant pop ups for me to opt into notifications, then an ad for the pro version, then an ad, then another notification pop up and then another pro offer before showing the skins} I managed to find one i liked but it stopped working. I then tried to fix this and its to no avail, I can no longer access the app at all. However, the ads still remained dispite the constant "something went went wrong" messages.

tf is happened??? I want to sign in but it keeps lagging and I can't log in even though I've pressed my email 5 times. when I want to open the skin that i want to download, it keeps loading and says 'something went wrong'. I've tried uninstalling and reinstalling it but nothing changes, geez.. I thought it was my wifi, but when I used my internet quota, it turned out to be the same, still lagging and loading

Constant ad spam on clicking any button such that it ruins the app itself. Edit due to dev response: While I understand that there are costs associated with a free app, it should not come at this significant of an obstruction to the user experience. Want to view a skin? Ad. Want to save a skin? Ad. Want to open a skin from storage? Ad. And these are all video ads with ~20 second skip timers. I've spent more time in ads than the actual app I'm trying to use.
