We are currently stuck at a high diff. It will take a while until that's resolved.
And transaction confirmations slow to a crawl... great...
So my wallet's transaction history gets littered with pages of conflicted generate transactions, and I can't even spend coins. I am certainly disappointed by the quality of this switch-over so far.
Lot's of mined coins came in after POS became active, but now they're all NOT accepted

, Is this normal?
It's normal after a switch.
Sounds more like a known bug that you didn't bother to fix. I would hardly say something like this is 'normal'.
I certainly hope the dev's get their shit together on this.
