Is it possible to send email from a public app?
I get this error:
If the app uses the USEREMAIL() function, it must require users to sign in. As currently configured, the behavior of this function is unpredictable and will stop working entirely on Jan 20, 2018. Please fix your app before that date.
I purchased the public Publisher Plus plan for this feature only (as it states on the website it supports automated email notifications).
Is it can work, then what’s the best way to go about this?
