I install the altstore 1.4.6 app on my iphone 6 iOS 12.5.4 (no jailbreak) from windows and works very well.
Now I'm trying to sign in with my apple ID and I can't, just keep loading and it never can goes through.
Its a known issue? I could not find any open/closed issue for this.
First i created a new apple id, install itunes & icoud on windows, logged in with this new account & did the same with the iphone. Then i installed the altstore & tried to signed in with this new account and 'failed' so I rebooted the phone and tried again, 3 attemps with no success. So basically used this account to the whole proccess.
Then i tried using my personal account to loged in into altstore while the new account was on the iphone. No success again.
My last try was with my personal account in the iphone & in the altstore, but once again i was not able to sign in.
