I just moved to a Samsung tablet from an ASUS Zenpad. I installed and configured Message+. Most of my conversations were restored, but I have one large one with messages going back many months. Most of the history is missing.
I also tried using SMS Backup to save the messages from my phone, but the Samsung tablet (using the same app) doesn't recognize the backup file, so I can't restore the messages.
Looking for help to...
1. Retrieve the messages within Message+
2. Use SMS Backup (or another app) to backup the messages on my Pixel phone and restore them on my Samsung tablet.
