I have not tried what user @JohnLi mentions.
Lately my workflow has changed a bit where I donāt do as much copy pasting in chunks. Rather, Iāve been pasting whole sections of text (when I paste large sections from web pages it seems to paste as plain text, not rich text) and then manipulating it from there. I havenāt seen the issue in the last few weeks. But Iām keeping an eye out for it.
That having been stated, I seems correct what he mentions. I seem to recall that if you fiddle with the order on the web client, that it resyncs the affected device. I would imagine that you have to go through the entire list like that so that the order it ātouchedā for each item.
