Outlook App keeps crashing on iPhone iOS 16.0.2

It seems to all start when you toggle off threads in the Outlook settings. The moment you touch that - the App crashes. The only way that I have found to fix this is to reset your phone, and then set it up again using an iCloud backup from a time when it works. It is working now

I am having the same problem - the app is crashing while opening. This started happening AFTER i noticed the email thread count being displayed even though the function was toggled OFF in the settings. I turned the organize by thread feature ON and the crashing started. I cleared cache, deleted the app, reinstalled and it keeps crashing.

Microsoft Outlook iPhone app updated one day ago to version 4.2238.0, on iOS 16.0.2

I have exactly the same problem on my iPhone. The App crashes before it even opens. I have cleared the cache, deleted the App and re-installed it, but with exactly the same result. Crashing before the App even opens,

In addition, on my iPad (no update) despite the toggle being off, the App on my iPad keeps sorting mail into threads. I cannot get it to stop doing that. This is also a new issue. Very irritating.

1. 4.2238.0, I can't provide a screenshot. Because it's keep crashing.
2. I can't because it's keep crashing.
3. This is the first time to install outlook on my new phone.
