adding privat scores to Musescore, isnt possible anymore

Aug 2, 2019

How can I add all my privat scores into Musescore on Ipad. It seems I can not open them anymore. The upload using Itune doesn't work anymore, even mailing the file to myself and the copy the file into Muscescore doesn't work anymore. Does anybody has an idea how to perform this? Help is more the welcome
