My Font - Myanmar Font

Until now, I never found an app that required me to log in with an account for a social media platform, but I need facebook to use the app! And as if that wasn’t enough, I can’t even find where to put font files in, which means that I either need to sign in with a facebook account (which I don’t have), or that it isn’t an option. I’m being as generous as I can while still being honest by giving the app 2 stars.

My phone is 12mini, version is 16.2 When I installed this app and also i install packages (font) that i like~~~i through all steps and all the ways are totally right (it’s shown in tutorial) but my font didn’t change and it’s stay like original. What’s actually happening and how i make it become change the new font that application gives?! Plz solve error ASAP!

My phone is iPhone 8. After updated iOS 12.1, my zawgyi font appeared wrong font . My friend told me to install Zawgyi 2009 . Even though it worked for 2 days, I still can’t read the message (in Burmese) that other friends sent. I don’t know what happens. I also heard iPhone 8 & X do not support the Burmese language. If anyone knows how to fix this issue, please help. Thank you!
