It seems I have also been experiencing the same. Updated the app a few days ago and suddenly back to episode 198. This is really weird. @teresawallace44 let us know if you hear anything. Thanks in advance.
Thanks for reply. My progress was saved the last time it could still connect. So it means i might have to redo it from about 148(level 2363) i am now at. 2454 so mighy loose abou 100 levels
