Hi all, I am trying to invite a guest user to our **unpublished app** using the invitation url. Unfortunately I continuously get the error “You are not allowed to use this app in Guest Mode. Please contact the app developer for more details.”

In the Zoom Marketplace the **Guest Mode** is enabled, but ’ **Guest Mode Testing** ’ is disabled (meaning AFAIK that I don’t need to set the local enableGuestModeTesting=true).

I tried setting the local enableGuestModeTesting=true in the guest local instance ( having **Guest Mode Testing** disabled in the Marketplace) and it starts working for the guest user.

I am assuming that until app is published, I can only invite guest participant but they would have to enable the local ‘enableGuestModeTesting’. Am I correct? We wouldn’t want to publish not knowing what the behaviour would be with Guest users, as they would be a big part of the app traffic.

Yes, before the app is published, local setting is required. Once it is set - the behavior is identical to the published app

I have both set guest mode locally and in the marketplace. the guest I’m testing with is a member of my account. Nevertheless, the participants screen says “You are not…”.

Nothing is sent to my server when she attempts to authorize collaboration so I assume there is nothing the server has to respond to in order to allow the collaboration.

What am I missing? are there any properties of the app itself which would preclude collaboration?
