a had an old paper wallet with a sats. To transfer the “paper wallet” sats to my umbrel wallet, I imported the private key to electrum and sent the amount to my umbrel wallet (from a 187… to a bc1…). The transaction shows up properly and has already 60 confirmations. So far so good.
Now I created a new bluewallet wallet on my IPhone by using the 24 word seed from the umbrel wallet. This works, all previous transactions show up except the “old paper wallet” transaction I sent to umbrel from electrum.
