Oh that is very strange, mine started to sync up at once when copied over the appdata folder

Hardware wallets seems to have mixed replies when I ask.
Some like hardware wallets some like cold wallets held in offline laptop.

Also I didnt get any answer yet how to dump priv key direct  to a hardware wallet.
Also one person just seems to lost 27btc on ledger on reddit and lots of people cant see why it happened yet. Even experts looking to it.  I didnt understand the issue of course but lots of people with high ratings I see were puzzled and never seen it before.

Someone said cosmic Ray's changes 1 bit of info during some process.
At first I thought they were joking but I see more people saying that is the only explanation.

I'm liking electrum with watch only atm.

But yeah its weird we have a different experience with the syncing up element of core
Can other verify this is the case please?

Your wallets will not start to sync without the password.entered first?
