Connection issue when try to use Yandex app password

Hello,

I am trying to connect to Yandex account with using Yandex App Password. When I create new account on “Accounts” tab, everthing is just fine. I can connect and use my Yandex account with no problem.

But when I reboot my desktop, Mailspring pop-up “Several of your accounts are having issues” and cannot connect to the account even if I push “Check Again” button.

The interesting thing is, when I go to “Reconnect” panel and try to connect with putting “same” app password, Mailspring connect the account and I use it as normal.

I am using Windows 10, doesn’t change app password when I try to reconnect and after reconnected with same password, everthing is running fine.

What is the problem and how can I fix that issue?

Here is the error details:

Mailspring Version: 1.9.2-6e14dad1
Platform: win32
Account State: sync_error
Account Provider: yandex
IMAP Server: imap.yandex.com
SMTP Server: smtp.yandex.com
