Did you grant the "All Files Access" permission? You can find that under your tablet settings->Apps, tap the three dots at the top right, then Special Access, then "All Files Access" and make sure it is toggled on for MobileSheets. Then MobileSheets should have no issues with accessing the SD card. Also make sure if you go to the tablet settings->Apps->MobileSheets->Permissions that the storage permission is listed as granted. Lastly, you can tap on the folder icon on the "Set the MobileSheets Storage Location", then tap on the SD card icon at the top and it should show any detected removable storage. If you tap the SD card in that popup, then navigate to a folder, you can pick any folder you'd like to store the library in.
