It's likely your Intercom account is linked to a separate Cobrowse.io account. When you install Cobrowse.io for Intercom, a new license key is generated for you. This may be different from an existing license key you are using when you signed up directly at https://cobrowse.io/register.
We are aware of a possible issue with React Native apps only, where the user consent prompt is hidden behind the Intercom SDK's UI, so it is not visible for the user to take action. To confirm this is what is happening, you can disable "Require user consent" from https://cobrowse.io/dashboard/settings and try to start a new session via Intercom.
Intercom requires users to have the "Can install, configure and delete apps" permission in order to "Login with Intercom", and therefore also the Cobrowse.io Messenger App. You may grant your users this permission in Settings -> General -> Teammates -> Edit.
To work around this problem, we have released the Cobrowse.io Inbox App, which lives in the sidebar of Intercom, and enables connecting to the end-user's device(s) with just one click.
