I have been using Alby Hub connected to my always on node for SN zapping and receiving. I zap through the NWC connect app added to umbrel through the Alby community app store. I use the Alby Hub to receive.
I live in an area where we lose power frequently. That's why I use a UPS for my node. We recently had a few brief power outages. I didn't lose the ability to zap after power was restored, but the receive connection was broken when I was logged out from Alby Hub. I wasn't paying attention, and realized my SATs were now building up in the SN wallet.
No big deal, I guess. I just wanted to point out this issue.
