We noticed that the Waldo app disappears when you use an "IOS" in a language other than English.
It took us some days to be able to reproduce this issue (because of the MS Team's cache) - we're sorry for that.
But now, we've caught it! The fix has been done and the app is being re-published right now.
It should be published by Microsoft by Wednesday, 1st February.
I'll keep you notified.
Sorry again for the inconvenience.
The Waldo app for MS Teams for IOS for non-english is now published!
You should now see the Waldo app when you use an non-english IOS.
Sorry again for the inconvenience,
Enjoy your day!
