Hello Achim,
This is most likely due to the bug with version 3.4.3 that was discussed here: https://zubersoft.com/mobilesheets/forum...p?tid=8307
If the first line of your file is blank, this will cause an error with version 3.4.3. Version 3.4.4 has been submitted and should be available within the next hour or two to fix this. I apologize for any inconvenience this has caused.
Mike
UPDATE:
The Google Play update looks like it's been approved. If you load the Google Play store app and search for MobileSheetsPro, you should see an option to update.
