My mobile client after login, getting this error and issue with loading the menu after selected the table.
Hello @N3Peter ,
You receive this error due to not selecting the default menu for the all Departments.
Main Menu > Manage > Settings > Departments > Select Related Department > Default Menu > Select your menu for this field. (Do this for all of your departments)
After selecting the default menu;
Restart SambaPOS Messaging Server from the Windows Services part and click on the Update Database button on the MC3 Login screen and then try to login on SambaPOS Mobile Client App.
If the issue still persists you can send your Anydesk ID via email to support@sambapos.com so we can check the situation.
