This is a strange issue…
I have 48 Guest users spread across 14 teams; some of these Guests are part of more than one team, and these this setup has been running without issue for about six months.
I recently setup private channels in each of my teams and began adding relevant Guests, but some Guest members no longer appear in the directory listing when adding members. For example: Joe User (Guest) is a member of My Team, but when I attempt to add him to My Private Channel, I can see other members in the dropdown list (including other guests), but not Joe. This affects 6 guest members across private channels in three of my teams, and to be clear: all of my teams have private channels, and all of those private channels include a subset of all of my guest users.
And if that's not strange enough: Joe User (Guest) can be added successfully to *some* private channels, but not others, so the issue doesn't lie with a particular guest or a particular channel/team. I can't figure out a pattern. Has anyone ran into an issue like this? I'm well below any thresholds on channel limits or guest user limits, too.

@Christopher Hoard YES – mobile (iOS) app exposed my guest user!
Thanks for that thread; it's the one I'd been searching for – I knew I couldn't have been the only one affected.

@Chris Webb Same behavior; cleared cache and removed specific cookies from Chrome 79 (*.microsoft.com, *.sharepoint.com etc). I opened an Incognito window for the fun of it; no change.

@arrthurr1111 , I knew I wasnt the only one with this issue! I was finally able to add the new external guest members to the private channel through the mobile app.

I experienced the same, some users don't show up for addition to private channels, but I could add them in the Android app.

I'm glad I found this thread. I've been pulling my hair out trying to figure out whether the issue was on my side or my guest's side setup. Apparently it's on neither. I never would have thought it would work on the mobile app and not desktop, Also, adding large batches of emails from excel is on the desktop.
Thanks everyone for the comments and links!

@arrthurr1111 So it seems that Private channel owner may be trying to add the guest by complete address - email@example.com. Can he try to add the guest by display name instead or by searching just searching partial display name ? I am seeing similar behavior in my test tenant where if the keyword is display name the search succeeds but fails for the full address.

@arrthurr1111 Figured this out for those who need to know like I did. I was able to add my Gmail account as a Guest to the root Team, but not sub channels, UNTIL I registered my Gmail account with Microsoft, creating a Microsoft account named my Gmail account. Once this registration was completed, the Online, Mobile App, and Desktop App all were able to find and add my Gmail named Microsoft account to the Channels.
In short, Teams is waiting on the guest user to register, THEN you can add the registered Microsoft account to Channels. Those that appear immediately have likely registered previously for services such as Microsoft Store or other products requiring a Microsoft account.
