Slack "Sync Thread" feature no longer available

[Sarah Green]

We rely heavily on the Sync Thread feature with the Slack integration - you post a message in a channel and the link preview shows an option to "Sync Thread" which syncs all messages in the thread to the comments in Jira.

I've noticed that the feature is stopped showing up - all the messages have the same formats to meet the integration requirement (add the link to the first message), but now they don't show up with the Sync Thread option in the link preview.

Example from the same user where it worked:

It is also affecting my users.

Having the same issue here, the Sync Thread option stopped appearing completely a few hours ago.

[Alexander Kraml]

Same here. Since 9th of October the Sync Thread option is not longer part of JIRA Slack integration. All users are affected.

Morning Everyone. One thing i noticed with this, is that when i copy a JIRA item link into a slack channel , it now says "Added by a bot".

So now it seems that SLACK / JIRA thinks that when a human manually pastes the jira link , that its done by a bot. 

This is why we are getting the ASSIGN button and not the SYNC THREADS.  this needs be "seen" as done by a human

i know its not an answer - but hopefully give the JIRA devs a heading on where to go
