Which is exactly why I only keep an experimental amount of sats on my Umbrel running on Pi 4 and have much more sats sitting on my Embassy Pro.

Umbrel seems to be in the camp of move fast and break things. The sheer number of apps added to their app store in the past year seems to align with this ethos. I would be very cautious and would limit the amount of sats I put on an Umbrel if I use one as a Lightning node.
