I updated AdvChart VCL this morning, and now I'm getting the following on IDE start:
Can't load package C:\Users\Public\Documents\Embarcadero\Studio\19.0\Bpl\AdvChartDEDXE11.bpl.Cannot
load package 'advchartdxe11.' It contains unit
'Data.Bind.ObserverLinks', which is also contained in package
'bindcomp250'.
Win10, Delphi Tokyo enterprise, advChart v 4.2.1.9 (8/27/2018).
