I don't really get NoorNode payments. I opened it today and saw I still owed 1105 Sats for the Premium Tier. Alright, I sent it over. Then it somehow switched me to the Standard Tier, and suddenly I've got over 11,000 Sats in credit. Now when I try to switch back to Premium, it presents me a new Lightning invoice. What's going on? @npub1h8lhe... @npub17veg2...
