Layer delamination - filament change

[Win_Or_Learn 0]

I'm 3D printing on an Ender 3 with Solutech PLA filament (1.75mm) and using an extension in Cura (4.4.0) to pause at a layer. At this point, I'm changing colors (same brand) and finishing out the print with the new color.  My problem is that the second color wants to delaminate from the original and I can essentially pull off all the new layers as a piece because it hasn't "stuck" properly to the original.  Thinking that the pause would result in the original layers to cool, I set the "standby temp" to 210.  Is there some other trick that will give me better adhesion?

pla is sensitive to temperature, keep the bed hot while switching filaments, and raise the temperature of the new filament higher
