Scheduled reminders in private channel

I have a problem with “scheduled reminders” that although the @github app is on the channel, it returns this message “The channel (my-channel) was not found. Check that it exists and that @github has been invited to it”

This channel on slack is private, but I don’t think that’s the problem.

Hi @deadc! :wave: Welcome to the Community!

Sorry it’s taken so long for someone to get to you. We’ve made quite a few improvements to scheduled reminders recently, and I think there were some changes to Slack’s API that caused some problems too. Are you still experiencing this issue?

If so, can you let me know what you see if you go into the relevant Slack channel and type /github please?

Could you also please confirm that the GitHub App in Slack has been explicitly granted access to the channel you’re trying to use?

We’re seeing the same issue on an organisation account. The channel exists in slack, we’ve invited GitHub App and granted permissions however in the GitHub UI it can’t see the channel.

“The channel (xxxx) was not found. Check that it exists and that @github has been invited to it”
