I'm not the best person to explain the how or why but they are looking at Q3 for beta and Q4 for main release.
I'm running Immich, Nextcloud and Jellyfin on TNS and it's fine. Nextcloud takes a bit of work though.
I've used expressvpn on an Asus router, using fusion to split different ip addresses onto different vans and its been sound, no issues. So much easier than I was expecting.
