OpenVpn issues Slate AX (GL-AXT1800). DNS issue

I am having some troubles with the device working as openvpn client, both with 4.0.0 beta4 and 4.0.0 beta8 (latest currently).
I configure openvpn connections to openvpn servers I can use with Flint and my personal laptop. Connection is successful but no internet connection.

Ok, it seems simply a DNS issue. I have to select manually the DNS servers or activate AdGuard Home to have the openvpn client working as expected.

The issue appears with the device working as openvpn client, AdGuard turned off and DNS Server Settings set to Automatic.
Is anyone having the same issue?

This seems an error in routing setup.

Did you install Avahi-daemon manually?

Hi, I did not install/modify anything before the test (I restored to factory settings to be sure).
The openvpn servers are 1) a Mango I own in another country 2) a paid openvpn provider with servers in EU/US/Asia. Both of them working ok with Flint and a pc client.
I can provide any log/detail to narrow down the problem.
Not sure if I am the unique beta tester with that issue, or perhaps they enabled AdGuard and they did not find the issue. To replicate the issue default dns config must be present (AdGuard off and DNS to automatic).

Issue solved in firmware 4.0.0 (release3), first stable release.
