Seems that Google changed authentication mechanism, now integration with Gmail required 2-steps verification set-on and define app password which should be use istead of account password.
I am trying to create an workaround for above 2GB jobs which can't be send from FFC to EFI DFE (by the way I do not know why). I add preflight to check file size, if exceed 2GB than want to sent notification to operator using Review components configured using Gmail account. Unfortunately it did not work (I did not get any e-mail) I don't know why. Any idea?
