AdGuardHome on GL routers

Dear developers,
on GL-B1300 there is a big problem with free Ram after adding a few filter-sources.
If you take a look in menu “Applications - Plug ins”, the amount of free Ram is 0%.

On my two B1300 devices, I am not able to change VPN-Settings, Kill-Switch setting and so on anymore. Even after a restart.

Checked it also on AR750s —> no problems.
