Hi! First of all thank for developing this fantastic plugin.
I have sendgrid configured and it seems to send emails perfectly, both through api and smtp.
But it is not receiving the bounces. In “Last run” always reads “none”. And after pressing “Force a run now” it shows an error: “Error on connection with HTTP code 403”. There are no other errors in the wordpress debug log or the inspector console.
Hi, sendgrid released a new library to connect to them and we already have an alpha release of sendgrid extension. Would you like to install it in your system to see if that new library works for you?
The extension is still compatible with the old methods, the new library can be switched on and off.
Since you should have the licence active can you open a ticket so I can send you a private link to get the new version of sendgrid?
