I would contact the developers directly for something like this send an email through the app via App Settings > Help > Report a Bug. This will open up an email which will get sent directly to the developers.
is adobe saying they refuse to help, and its too bad soo sad poor people lost their sketch projects? I'm losing notes from school, not pretty butterflies. This attack on poor people is par for course with big businesses. thanks for the frustration and extraordinary circumstances that my instructor will not excuse
Sorry to hear about the trouble you are facing. If you are able to locate your files on this website (https://adobe.ly/3eoSI3p) then, I would suggest you check out this video (https://bit.ly/3qfAz0Q).
