maybe I didn't understand or you misunderstood me
but overall my wallet is synchronized, but I turn it on once a day. But every time I have to wait a long time when the blocks are synchronized in the last 24 hours. Previously, before the change of the algorithm, everything was faster.
I have an office processor (G3250, standart HDD) - 10 hours synchronized in a few minutes.
