Description

When posting message to multiple channels ('channels: "#mychannel, #secondchannel") messages work as expected. But when return-value is stored to variable and using the update-message feature (channels: previous_message.channel_id, timestamp: previous_message.ts), only the first channel message gets updated.

is it possible with curl to update messages across multiple channels?

I haven't tested, not that familiar with slack API. Quickly checking the API it looks like it looks like you could just post message on one channel at a time, but either case if slack-plugin splits up the posts, I would expect to have array of channel_ids to update messages on return-object.
