Nothing changed in terms of functionality, but you're now looking at a way increased network difficulty compared to 6 months ago. Meaning transactions carrying a similar amount of coins would now take longer to find a block.
If you would like me to check, whether everything is in order, you could PM me a screenshot of your wallet with the minting tab open.
Thank you. It might take a day or two. It's on a Mac that I'm not using that much.
Low uptime certainly would be a factor as well. In an ideal case you would be staking on machine that is running 24/7.
Staking is messed up. No way that coins with highest mint probability was not still minted after wallet update. The higher amount coins, the lower mint probability, despite what I see in mint probability column. Can't be that big chunk of coins never minted after update, it was 230 days 30x bigger probability and nothing. Look's like bigger amount are forbidden from staking.
