I’ve been using webhooks for 2+ years and 20 active zaps, no issues.
The last 5 i’ve tried to setup all are not receiving same data to test. 

Zapier support traced an error code to: Error: You don't have access to the "" app anymore.

I have no idea what this means, as no webhook structure has changed.

Does anyone have further information on this or know how to resolve?

Thanks!
