This issue needs support from the API. The root cause is that on event notification.removed_from_channel the SDK is not calling channel.stopWatching(). As a result of that the mentions suggestion list still contains channel watchers that have been removed as members from the channel.

cc @totalimmersion - a user cannot stop watching a channel a from which it was previously removed.

I have a similar issue where users invited are displayed on the mentioned list, I need to show only users who accepted the invite, how can I achieve this?
