I have the same issue and after trying all the steps from letourneau6 to no avail, I came up with two solutions of my own. They are a bit of an extra step but if you have this version you probably don’t mind it... the first way to get it working is to open the app then switch to settings app and change the date back a couple weeks. Then switch back to the app and it’ll be fine until you close it again or save a song... that became a pain because it makes you go back one more day each time you do it for some reason... the second solution made it much simpler tho.. open the app and within a second or two hold down home button for Siri to pop up... wait until Siri loads all the way and don’t do anything with her.. then just switch back to sing and boom you’re good... I included both solutions just in case either might inspire a fix for the creator of this ipa hack. Thanks so much
