Worth checking where Core has got to in the sync process too. From the Bitcoin Core client go to Help > Debug Window > Information.
In Core 0.18 this was moved to the Window menu. So Window > Information.
Check that the value next to "Current number of blocks" is greater than 579853
Core Information: Current block = 579869 Last Block = Sat June 8th 16:50:17 2019
Looks good.
Armory still stuck at 28%, 169113................
I'll let it play out for awhile
