Channel creation missing members

[Problem/Question]
We have a platform for patients to talk to clinics that are our partners. Our patients can also talk directly to us for non-health related info (i.e. account questions, invoice,…)

We have a default application in senbird, called Default.
For each clinic, we create a separate application (Clinic1, Clinic2, Clinic3,…)

When a patient signs up for an account, we create a SendBird user in application Default.
When an employee of our company creates an account, we create a Sendbird user in application Default.
When an employee of our partner clinic creates an account, we create a Sendbird user in the appropriate clinic (i.e. Clinic A).

We have no problems creating channels for the patient to talk to us in the Default application.

When a patient wants to talk to a Clinic, we create a channel with:

  1. The patient (created in the Default application)
  2. Members of the appropriate clinic (i.e. Clinic A)
  3. Selected members of our patient management team (created in the Default application)

When we go to create the channel, we are seeing either (we can’t figure out the pattern)

  1. Certain users are excluded, so the channel is created without all the users we specify
  2. A channel is created with 0 users

Here’s an example of our call to create a channel between patient and a clinic:
