I dont know the answer to your question, but your comparisson above make no sense.
Thats like saying:
Today it took me 30 minutes to get to work
Last week with my old car it only took me 15 minutes.
You share no information about the traffic situation (how many unconfirmed TX, what fees they paid, how was the situation in the block before the TX's) which is the main indicator whether the estimated fee is good or not.
Shouldn't a new release put more features in the system?
Apologies for OT: I didn't want to go out of this "support thread" next time I will give more information.
As this issue is now resolved I won't give them now.
Thanks brianddk for help and everyone that gave info.
Thanks.
