Channel Members are still visible after leaving a channel

[ondrejkorol]

Hi. We’re getting reports that sometimes users who left a channel are still visible to other users.
My assumption is that there is some kind of cache issue.

It’s easy to replicate it within the Example app.
You’ll need two devices or simulators and pick two random accounts. For example:

As Luke Skywalker

• Create a group chat and add Leia Organa

As Leia O.

• Open the group chat.

If Luke S. leaves the group chat while Leia has the app open,

• he’ll be correctly removed on his device, on BE, and on Leia’s device ✅

If Luke S. leaves the group chat while Leia has the app closed,

• he’ll be correctly removed on his device, on BE, but ✅
• he’ll stay visible as a channel member on Leia’s device ❌ (lastActiveMembers still returns Luke; unless you log out on that device, which clears the cache)
