I've installed ACR 3.0 Free on a Huawei P8 lite 2017 cellular running Android 7.0
I've got 264 recordings listed on ACR and saved them via Backup to backup folder on an external SD Card.
After that, I cleaned ACR by deleting files on
Once done, I've restored some recordings copying (manually) the exported recordings files from the backup folder to the ACR cleaned one.
Then I uninstalled ACR and installed it back (3.0 too) from Google Play.
Once completed the initial setup of ACR I launched the Database Maintainance but nothing appears on the ACR main screen.
For sure I've checked that the files are right in their place, but this seems not enough to get the ACR database recreated with them.
Then, if this is not a bug, ¿how a restore has to be performed?
