Same experience here - I no longer can even cast from the new app because the cast list is just empty. My partner can cast from iOS, but the new iOS app design doesn’t appear to have a playback settings menu during cast playback, so we’re forced to transcode instead of direct stream. It also has fits of buffering several times a day when LAN streaming.
I have Jellyfin running in parallel but the only Jellyfin app I really find palatable is Findroid on android TV but it’s kinda in alpha right now
Since you want to avoid supports and cleanup, what I would do is modify the model to flatten out the inside of the dome. You can do it easily in most slicers by adding a cylinder part and squishing it until it’s more like a disc.
A flat roof to the inside of the dome will cause it to switch to bridging for that section which won’t be perfect but will be a lot better than stringing, especially if you play around with thick bridges.
