The screenshots make the difference clear: the 340-reply thread reaches the July 22 message when opened from the channel, while the Teams-generated permalink stops at an older message in both desktop and web. That points to a reproducible thread-navigation issue rather than permissions, because the same users can see the missing replies through the channel path.

 

Ask an admin to check Microsoft 365 Service health for a Teams advisory and use Report an issue if none matches. Reproduce once more, record the exact UTC time, then collect Teams support files with Ctrl+Alt+Shift+1. In Teams, choose Settings and more > Feedback > Report a problem and attach the screenshots. Include the permalink, tenant, team, channel, thread/message identifiers, affected users, and Teams versions. If no advisory appears, the admin should open Support > New service request. Meanwhile, use the channel reply count or Go to channel to reach the complete thread.
