Ppl tutor app
My daughter recently downloaded the ppl tutor app for her air law found it very helpful and so bought all the revision content and exams, and now the app isn't working- we have tried deleting the app which caused it to start up again but then when we clicked to restore previous purchases it went back to not working (all that's coming up is the title and the clouds moving), we have also tried emailing them but they haven't replied as of yet- and ideas how to fix it/anyone else had this problem?
