I moved from a Pixel 2 to a Pixel 8. I transferred everything from my Pixel 2 (apps, settings, texts, files, etc) using the Pixel 2 backup on Google One. After I activated the Pixel 8, I check to see if all of my Verizon Messages (texts) transferred over, and it appears that some group MMS did not transfer over. For example, one group MMS only goes back as far as October 7, 2023. Why didn't all of the group MMS messages in Verizon Messages transfer over since they were backed up on my Pixel 2?
