Only one vault can be opened on IOS through OneDrive

I have two vaults on OneDrive. Both work well on my computer of Win 11 and Android phone.

However, when I add the two vaults on my iPhone 15, the first added vault can be opened without any issue. The second one shows Content Unavailable - the folder cannot be displayed because of an unknown error.

If I remove the first vault, the second one will work. When I add the first one back, it will show the same error until I remove the second vault.

How can I make both Vaults work on my iPhone?

Thank you
