GL-ATX1800 Not Retaining Allow List

I’ve been implementing an Allow List for my devices under Clients successfully for months. A problem with the GLiNet iOS app led me to check my web configuration and so I noticed that my Allow List was disappeared. I thought “hack” at first but after a search, I came across this post…

and so it seems to be a bug in the 1800 Flint 1 firmware? And no fix listed?

So I upgraded from firmware 4.6.8 to beta 4.8.2 firmware but the same problem persists even after rebooting the router.

I really count on the Allow List to add a layer of protection against close proximity actors in my area.

What is the fix for this problem?

Resetting my router seems to have fixed it.
