Despite dynamic fees, my latest transactions toke also few hours to be completed yesterday.
So, I guess the network is a little bit slow at this time.
Regards
the network is not slow, it is working as it should and same number of blocks are being found as always with the same size.
what is different is the number of transactions that are happening. in other words the number of transactions in mempool waiting to be confirmed has gone up drastically (probably a big part of it is a spam attack again) and this means miners will choose the highest paying transactions first and then go to high fees and medium fees.
