v.1.6.3: still can't login to the 7th account

Update: it was not just the 7th account. It was because Bulwark still doesn't support Stalwart 0.16?, Please delete this post

The change log says it now supports unlimited accounts due to the http/2 implementation.

I've inspected the browser network, and the protocol is 'h2'.

I can log in to up to 6 email accounts, but when I tried the 7th account, it reported Invalid email or password. Please check your credentials and try again.

I tried the 7th account with my other accounts, and it reported the same. I'm sure I entered the correct passwords.

I'm not sure I need to set some settings to make it work?
