Hi @KeithBurdette1,
This issue is related to the migration of Survey123 data from 'public' storage on the device, to application-specific 'private' storage on the device. This was a Google Play Store requirement which affected the 3.12 release on Android and all future releases. Please refer to the following support article:

It would appear the migration process is getting stuck or failing when copying the existing data over to the new location. This can happen for several reasons as per the above link. If there are no draft surveys, unsent surveys, existing attachments or other survey data that was previously used with the 3.11 version of the app, that has not yet been sent and confirmed stored successfully in the feature layer, you can simply remove the 'ArcGIS' folder in the 'public' storage location. When you install 3.12 again, it will create the required folders and new data paths in the 'private' location, without trying to migrate the existing data across.
The 'public' data location is: /Internal storage/ArcGIS/
I would suggest to copy the 'ArcGIS' folder to a PC or zip it up as an archive on the device or SD card, before deleting it. Then install 3.12 again from the Google Play Store, and it should work as expected. You will need to sign in and download the needed surveys again.
Hope this helps.
Regards,
Phil.
