The MR36H access points have a different configuration setup compared to the MS series switches. The MR36H is designed with integrated Ethernet ports that behave like access ports on a switch, and they will not accept incoming traffic if it has a VLAN (802.1q) tag applied. This means that each port on the MR36H can be associated with a single SSID, which in turn can be associated with a single VLAN.
For your specific use case, where you need both data and voice VLANs accessible through a single port, the MR36H might not function in the same way as an MS switch. The MR36H's ports are designed to provide connectivity for a single VLAN associated with a selected SSID. This is why you had to create separate SSIDs for each VLAN and apply them to different ports on the MR36H.
There is a way to set per-SSID VLAN tagging in the Meraki Dashboard, which allows you to configure SSID-wide single VLAN tags or per-AP multiple VLAN tags. This feature is typically used to extend VLANs from your wired network to your wireless network. While this doesn't change the fact that each port on the MR36H is still limited to a single VLAN, it does provide flexibility in managing VLANs across your wireless network.
If you require a port to handle multiple VLANs (data and voice), you might need to consider using a separate MS series switch in conjunction with the MR36H.
