So I understand this correctly, you’re using Fossify Calendar as the phone app that accesses your self-hosted calendar?

I prefer micro fiber cloth and rubbing alcohol. There’s an stl where you cut the micro fiber into strips and attach it to thee face of a “scrubber”. Gives you a handle ti hold and a flat surface to put against the print plate.

The arrs would be your best bet to reduce your input. If i’m not mistaken you can run them all through docker including a version of qbittorrentb that’s bound to a vpn and the only way it access the internet is through that vpn. Or you could split tunnel your vpn and bind your qbittorrent to it and bipass your jellyfin instance.
