All of a sudden the plugin does not transmit requests to the SendInBlue service. It worked last month.
I am not getting any error messages. No request is received at SendInBlue while it was send from my Bubble.io app.
I have regenerated API Keys and redeployed the app but with no avail.
Please help.

Hello, @emdr.il.dev1.
Thank you for your patience and question. 
We have checked the plugin work on our demo page and a few test apps with this plugin - the issue you have reported is not reproducing there.
You can check your application Logs to see if the Sendinblue workflow was performed successfully or check browser console. Also I can recommend contacting Sendinblue support in case if they maybe suspended your account for some reason.
Hope it helps.
