Edit:
Solved! Turns out this was not an OPNSense issue, but an Omada AP firmware issue: https://community.tp-link.com/en/business/forum/topic/593488
What tipped me off is that there were no ipv6 issues when using a wired connection.

Hello all
I'm fairly new to OPNSense. Everything has been going well so far, except I'm having some trouble with ipv6
I have Xfinity (Comast) - I'm able to get ipv6 addresses, and I have it set up on my LAN and a single VLAN right now (For testing purposes)
When I connect to my LAN, I get an ipv6 address, and I am able to ping and send and receive data: https://pastebin.com/raw/MY28qAy0
When I connect to my VLAN, I also still get an ipv6 address, I am still able to ping, but it appears that packets are not able to route back to me?: https://pastebin.com/raw/nP9uC2n5
Here's all the configuration that I think is relevant. Any help or guidance would be greatly appreciated.

Edit: I captured some packets, and I see that the interface is getting a response, but it seems the packets are just not getting routed back to the client (https://i.ibb.co/BPDbtPX/Screen-Shot-2023-09-14-at-12-57-10-AM.png).
