Don't you love when your trying something technical for the first time & it doesn't work for a totally unrelated issue?
Wanted to try exporting a watch-only wallet from my ColdCard Q to Nunchuk & it seemed to work, but every one I tried showed no history (which is always a little panic-inducing.)
It turned out that despite the5G indicator, my phone basically had no working internet. After I also noticed issues trying to use nostr I rebooted the phone & everything synched up & worked fine.
