Ratings and reviews

I've been using this wallet for years without issues. That said I had the device off mostly. But when I needed to use my wallet it worked every time. The device it was installed on is dead so I installed on a newer device and restored one of my accounts with the passphrase. This process worked and I know the phrase is correct but it won't connect to a server and shows zero balance whilst constantly refreshing over night but still no server connection and balance is zero. I'm having a cold sweat.

I've used it for years and it's been great. My one gripe, which very very rarely pops up, is sometimes the transaction doesn't broadcast properly, meaning I need to import my xpriv into another wallet, possibly wait for it to sync, and (re?)broadcast it myself. Not sure if adding an RBF flag would help me just "double spend" on my own, but then again I don't want everything RBF. It's happened maybe 3 times over the last 4 years. Likely could be fixed by now, but it was a pain when it happened.

Decent wallet, QR code scanning doesn't work in app, yet I'm able to scan with regular camera app and the link works. that doesn't make any sense
