I accidentally deleted my notes on the memo app on 2016 A3. Now i go the cloud and it shows me 3000 and something notes and its mbs, but it says that is from a discontinued app (and is S Note) and only give me the option to delete it. What can i do to get my notes back?
You could check to see if you can download the discontinued app from apk mirror & see if you are able to install it on your device.
See if that allows you to recover your notes?
