You're welcome, I am here for the community 👍
One of the Proton Linux devs just commented about that over in the Proton VPN subreddit:
We're going to work on it, there are some issues with the DNS resolver that debian uses, which is not the same as Ubuntu and Fedora, which makes split tunneling behave in an unexpected manner.
Out of curiosity, are you or any of the other mods with Proton officially? I appreciate the updates regardless, I was curious if this was an official / unofficial community
We are the same volunteering moderators as on all the Proton subreddits. Official in that way and that the owner of the board here is the Proton account beloging to the team, unofficial in the way that the Proton Team isn't really present here.
Do you still need help or did you get it sorted?
There are some good signals for now and it is unlikely this will pass:

The Federal Council's plans to revise the Ordinance on the Surveillance of Postal and Telecommunications Traffic (Vüpf) have failed the consultation process: All major parties and numerous associations clearly rejected the plan.

Such a unified opinion across all parties in Switzerland is rare. This topic has also made the rounds in swiss medias recently with a big echo, it is fought by many swiss organisations and companies and as example Proton will leave Switzerland if it were to somehow pass anyway: https://www.techradar.com/vpn/vpn-privacy-security/we-would-be-less-confidential-than-google-proton-threatens-to-quit-switzerland-over-new-surveillance-law
I copy the annoucements over here from reddit.
Legal HQ is in the USA
Please feel free to send that feedback directly to the Proton team through a support ticket
Android, Linux and Windows already have custom DNS support:
Still planned for summer, which in Switzerland (HQ of Proton) is until 22nd September
