Can't load Trello Board after iOS recent update 4.1.10

[Trd 3]

I have problem accessing some of my board using iOS device after 4.1.10 update.
However, I CAN access the same board using Chrome/Safari or Android version of Trello. (My device iPhone 8 plus/ iPad mini 3)

I have tried
1. Clear cache on launch
2. Delete and re-install app
3. Re-log

The board I'm using has lots of attachment and about 230 open cards. But I don't think it is not the issue because I can access the same board with Android devices.

Any advice? Thank You

Hmm, that's definitely odd! Would you mind reaching out to us at trello.com/contact so we can take a closer look and further troubleshoot this with you?

Thanks so much!
