Some users unable to make use of group direct messages

Issue summary:
On March 22, 2021 from around 11:24 a.m. to 2:38 p.m. PDT, some users were unable to make use of one or more of their group direct messages (DMs).

This trouble, such as seeing a blank conversation or seeing an error message when attempting to star the conversation, was caused by a code change. We reverted the code change to prevent this from occurring with additional group DMs. We also corrected the trouble this caused for group DMs that were already impacted.

If the group DM still isn't working as expected, please refresh (Control/Command + Shift + R). If the group DM appears twice, please let us know at, and we'll send you steps to clear cache.

Note: We've updated the title, as this issue affected other group DM features beyond viewing the conversation.

6:10 PM PST

Affected users should be able to use these group DMs again. Please refresh (Control/Command + Shift + R), if the messages haven't loaded yet.

We apologize for the interruption, and we'll be back with a summary.

3:02 PM PST

We're continuing to work on a fix, and we appreciate your patience.

Some users may also be unable to receive notifications for and take actions, such as starring the conversation, on affected group DMs.

1:57 PM PST

Some group direct messages (DMs) are appearing blank. We're working on a fix, and we're sorry for the trouble.
