Hello Yisroel,
Thanks for reaching out to the community. Gmail is not following Microsofts path on this decision.
They did, however, make it so that you need to use an app password for everything that connects externally. This requires 2FA to be enabled on the Gmail side.
Please see this help doc for how to get Gmail working with SmarterTrack.
Please let me know if this helps and if you have any questions.
Kind Regards,
Zach Sylvester
