No vlan 1 possible?

Hi, I am new to cambium. I try to configure 21 APs via cnMaestro x. After onboarding the APs get a config with only vlan 72 (Management) and vlan 73 and 74(for the SSIDs). There is no vlan 1 after onboarding. But the APs seem to be unable to communicate with the cambium cloud on 72-74. All vlans have Internet Access.
Is it nessessary to have a vlan with the ID 1 for the APs?

Thank you

Can you share AP config?
