Firmware 6.10.2 cannot configure email alerts

I updated my firmware to version 6.10.2 and figured this would be as good a time as any to try to get email alerts working again (they haven't worked for a while).  I did have it set up to use Google via SMTP, which stopped working when Google started requiring stricter security than just username/password authentication.  After I updated the firmware, I went to settings and selected "Clear" to remove the old mail settings, then hit the "Google" button.  It had me sign into Google, Google asked for my permission to allow ReadyNAS Email Notification, ReadyNAS asked me to verify my IP address, and everything seemed to go OK, except that when it returned to the settings page, it had an error message saying "SMTP Server cannot be empty".  These are the settings (all greyed out and non-editable) that were put in after doing this:

User:  (my email address)

Password:  (a bunch of dots)

Email Provider:  Custom

SMTP Server:  (blank)

SMTP Port:  (blank)

From:  (my email address)

Use TLS:  (blank)

I'm assuming some kind of token-based authentication is going on here.  Is it a bug that the server/port information isn't getting autofilled and won't let me edit it?  Maybe a bug that it won't let it be blank, since presumably it should know where that stuff is for Google email?

It's impossible for me to set up my email alerts right now.  I tried a Microsoft account as well with the exact same result.

Thanks in advance if anyone's found a workaround.
