Update: I did not realize that L-BTC was needed for fees, and L-USDT would not cover the fees to transfer the L-USDT. This was my first experience with Jade Plus and Green Wallet. I want to retract my statement that this is a beta product. For example, I think the product needs better error message handling and improved UI. For example, the error could have been 'Fee needs to be in L-BTC form and not L-USDT form' instead of 'Insufficient funds, ' which I felt was incorrect. Adam Back responded to my rant on X and helped me uncover the problem. So their support has been quite incredible on the matter! I wish I could edit the original post and reduce the harsh messaging, but I don't have the option. So, if anyone from Blockstream is reading the original post, my sincere apologies for the tone.
