so what to do if google does not send this notification?Please don't use the option to configure email and password as this will fail if you have 2FA enabled and you surely should have. Instead you should use standard OAUTH and when MacroDroid tries to send an email the first time you should see a notification displayed from Google to grant MacroDroid access to send emails.
I am sorry for this. I didn't know about it and bought it right away, it's working now. sorry thanksOne thing I should also point out is that if you are using a stolen pirate version of the app then sending emails won't work because it relies on the app being signed with the correct key. I'm not saying that's the case here but I get some users who do this and then complain about it.
