i tried connecting it to my umbrel LND node using the alby NWC app, got an error. something about length of string
Do you have a screenshot? You have installed it through the alby community store? https://app.supademo.com/demo/clyrcc5ao0e5ez9kdnu6vls08 (official release will be coming soon to umbrel)
im not using alby hub, using a normal LND node running on my umbrel with your guys' NWC app connected it
