After restoring to new iPhones from backup, the Photos tab in iMessage contact info is missing or incomplete.
Steps to Reproduce:
Restore new iPhone from iCloud/iTunes backup.
Open iMessage → select a contact → tap name at top.
Check for Photos tab.
Expected Result:
Photos tab should appear consistently and show the full history of shared photos (hundreds dating back to 2016).
Actual Result:
On some contacts (including mine), the Photos tab is missing entirely.
When it does appear, it only shows a partial set of photos.
Same behavior observed on both my phone and my wife’s, and also reported by other contacts.
