From blond to black - extension color shock

I'm having a rough time with fusion now that I'm dark when I used to love it when I was blond.

I used to be all shades of blond and blond/brown for years, sometimes with colors like purple and pink mixed in. The fusion glue aging and eventually turning white/gummy was no problem cuz my hair was so light it blended in. I felt like I was doing well with fusion.

But now that I've gone black/brown, when the fusion glue eventually goes white it shows up terribly and looks like I have serious weirdness going on in my hair. So I'm looking for alternatives.

Any advice for a new dark hair ext girl? What to try, what not to try?

I'll try that
I do tend to rush through the bottom layers and those are the ones that go white on me first

thanks!
I'll try to heat them well and roll them tight this time. I'll let you know what happens
