upgraded to a pro version – Ultimate Music Theory Review

i upgraded it to a pro version a year ago. studied for a while. the app is good by itself and helps a lot with studies. but, i left the study for a few months and when returned, my progress data was lost. the data was lost and my membership that upgraded to pro was also lost. i spend a couple of hours to trying figure out how to restore my purchase. so far nothing. waiting for the company's reply. this app is making very hard for you to restore your purchase. the restore process is long and stressful comparing to the other apps that have 'restore' purchase button.
