In our Airtable set up, we have to have a base per customer. I started linking each base to notify a Slack channel when a base was modified. Everything was going smoothly until I had 30 Slack channels. At that point when I would go to connect the base the new Slack channel was not visible. I tried a few more and it is a consistent result. I reached out to Slack support and they said it is not a Slack limitation. I cannot find any reference in Airtable about a limit. Has anyone run across this?
Problem solved… Thank you Airtable support for the email reply. Not all Slack channels show up in the view when connecting but search works just fine. No limits on number of bases to number of Slack channels.
