Hey there @joy 
I hope you’ve been well, and many thanks for the recent 1.2 CM update.
I just wanted to report a possible bug with the SMTP feature. This is not related to the latest 1.2 update, I was actually testing it already in 1.7 with the same results.
In particular, I seem to be having issues with Brevo (Sendinblue).
The API connection doesn’t seem to work, I can’t seem to connect via API key. This throws an error when trying to send the test mail.
For the regular SMTP username & password option, this works, I can connect, I can send a test mail just fine, however this is now causing an issue with my Bricksforge Pro Forms.
The form sends, and I receive an email, but the form notification returns an error.
I’ve tried to disable the CM SMTP and just use FluentSMTP plugin, and everything seems to work just fine.
Would you be able to look into this please?
Many thanks, Yann
