I had an Umbrel (homemade) running the BTC blockchain for a year or two, and about 5 or 6 months ago, they upgraded to version 2.0 (I believe), and it broke. I spent a good deal of time and never got it back. I then tried up $300 and bought their own server device and got it here, plugged it in, and upgraded to the latest version. Then, it would not load anything from the app store. The app store itself would pull up. Everything seemed to work, but it would act like it was downloading, but just stop and sit and eventually disappear. I had the Umbrel team remote in twice and never could fix it. They even sent another and the same thing. I really wanted it to work, but it was unbelievable what I went through and finally got a refund.
