Hey Munti, thanks for the reply.
The reason I'm wondering if I'm not on the right chains is because I use two other POS wallets, and while I occasionally get an unaccepted mine transaction on those, my BitBay wallet has had a number of mined transactions at this point, and none have been accepted.
That's only happened on one occasion with one of my other POS wallets when I had forgotten to download the new wallet version and was told I was not on the correct chain on their slack. After downloading the new version of that wallet, the issue went away and the majority of my transactions were accepted.
As far as I can tell, I'm on v2.0.0.0 of the QT wallet and I've left my wallet online since the earlier posts but none of my transactions have been accepted.
I restarted the wallet to see if that fixed it, but everything is still coming through as a "?".
Any ideas how to fix it? Or maybe it's just very common to have unaccepted transactions with the BitBay wallet?
