Wireguard DNS not resolving after migration

I migrated from a Gold SE to Gold Pro. Migration was successful and settings seem 1:1 but Wireguard clients don't resolve DNS anymore.

Before the migration, with default profiles. Default Wg DNS 10.200.169.1. DNS Booster enabled. DNS just worked as it should.

After the migration, with the previous settings, DNS does not work. DNS Booster is not pointing the LAN DNS as it should.
To make it work now, I'm manually modifying the wg profile to point to my DNS and I need to disable DNS Booster for that profile.

Just in general, DNS booster doesn't seem to work correctly. Our printer also has the occasional error now.

I went through a bunch of commands together with ChatGPT but couldn't come to a solution: https://chatgpt.com/share/6ac7aea1-dc10-83eb-8bb0-31c0e2c602b2

What are my options? I'm not seeing a single difference in settings with the previous Gold SE. Should I put the Gold SE back, reset the Gold Pro and migrate again? Is that even an option?
Is there a setting for DNS Booster? I am not seeing it (except to enable or disable per device).

I would really like to go back to the original functionality because DNS Booster is really useful.

All help is welcome because a lot of people depend on this Firewall and I was the one that advised Firewalla. Thank you.

Let me create a ticket for you. The only issue may be when you get a new router, your ISP may give you a different public IP, and that may influence the DDNS side only (and should clear up in less than 4 hours).

I am not aware inside changing, should all stay the same (wireguard gateway for example)
