Multy X logs

So if I understand correctly, SSH login is only provided as a backdoor for remote control by Zyxel staff and there is no logging visible to the user? There isn't even a web interface (well, technically there is: entering Multy's IP-address redirects to /gui and shows 404 Not Found) so if the app stops working, which it does sometimes for unknown reasons, I have no control over the network.

Why Zyxel is treating their customers like they are complete idiots and hide behind GDPR instead of offering a local log dump is beyond me. Every other wifi system I have been using (from Netgear, Linksys and AVM) have useful logging and offer some level of control to their users. I was experiencing network problems today and the logs in the app were not giving information at all. I only could solve the problem by rebooting the Multy's in a certain order, I have no clue what went wrong or what caused it and I have no idea if it will happen again. The wifi network is working now, but I don't feel confident it will keep working and I am not going to buy another Zyxel product offering this low level of control...
