I tried running gmail api watch on my two gmail accounts and it works fine.
But when another user tried to do this, it shows this error:
HTTP Error 400: "Only one custom client notification client is allowed per developer (call / stop, then try again)">
I donβt know if the problem is in the pub / sub client configuration or if stopping and viewing resolves the problem?
Can someone explain the meaning of this statement: "Only one custom client of client notifications is allowed for each developer"?
