I just started a free trial to check out the Slack integration, but my saved for later messages don’t pop up in my Checkvist Inbox list (I changed this from the default Slack Inbox list).
The docs also suggest, that a list of connected Slack accounts should show up in the tools section, but it doesn’t. I can see the app however in my Slack account with all the necessary permissions.
Looks like your Slack requests reach our servers but the message is not created. I’ve added more debug logging, may I ask you to try to try marking Slack message for later one more time?
Also, on https://beta.checkvist.com you should be able to select a target list for your Slack messages on the Tools page (currently it looks like you’ve deleted the corresponding list).
I selected a target list (in the prod version, not the beta version) - it’s the “Inbox” list. I did it again now, and funny enough, it seems to work just fine now. So I guess it was just a temporary issue?
