After I have uploaded my HamRadioDeLuxe ADIF file into QRZ.com, the new QSO's are almost immediately shown in the logbook view, but it takes sometimes well over one day before they show up in my manageable logbook. Why is that?
I've found a resolution to the problem. Go to the search field of the manageable logbook and enter a callsign with which you had a QSO, but which doesn't show up yet in the manageable logbook. This will show a result. Thereafter - much to my surprise - all other new callsigns suddenly showed up in the manageable logbook.
I've had no such experiences with LoTW, eQSL and Hamlog.eu. But then again it is not a big issue if this resolves the problem.
I have had similar success in resolving the problem of getting new records to show. In my case I clicked on the "Refresh Page" icon (circular arrows) near the bottom of the Control tab portion of the Logbook.
