It's true, but I'm having a hard time finding one of those so I figured I would at least try here thanks

So I use this amazing mobile app called Phonto on my Galaxy, and it's generally easy to install fonts onto it: I just have to click on the font in my notifications after downloading it, and it takes me to the app where I can press install. A while back it started taking me to only a blank screen, so I had to then go into my files, extract each font, and then install from there. Now, though, it isn't letting me install at all, no matter what I try. I've tried restarting my phone and reinstalling the app. The issue is most likely with the app, as the font files are downloaded just fine onto my phone, but I have a batch of fonts I really need to install and I'm at a loss. Does anybody else use Phonto, or have an idea on what I can try?
