Obimy app - impossible to log in via Apple ID - what you can do?

a lot of people are asking uh in the vimeo reviews section that it's actually impossible to log in with apple id or create an account with apple id for some people on ios devices apple id is messed up and i couldn't make an account with it so i made an account on my old phone if you already have an account and you're trying to lock an app it doesn't work it only yeah so if you know me it only gives you the option to log in with apple and people is a conscript account or just can't login so developer response is that we are working on it and soon it will be added an option to sign in through email hope that is helpful
