If you have a public channel, where the "Similar Channels" tab is visible, and then you switch that channel to "Private", you will still be able to see the "Similar Channels" tab. Additionally, the channel will still recommend similar channels with a welcome announcement to people who subscribe while the channel is private. When a channel is private, no information about similar channels should appear. This is creating huge problems for channels that do not want a new member to know who their competition is when they join.
Steps to reproduce
1- Must have a public channel with "Similar channels" tab enabled, so it can't be a new channel
2- Change the channel to private
3- One month later after changing the channel to private, "Similar Channels" tab and announcements are displayed to members.
4- On channels where you don't want your subscribers to know about other competing channels, this can be a big problem.
When I change it to private it still detects it as public and continues with the same functionalities, good contribution 👍.
