Annealing plated cases
Are there any issues with annealing nickel plated brass cases?

No problem at all. Watch your temp as you cannot see the brass change color.

Was going to ask that question, I presume a temperature crayon or similar would be needed to indicate the correct temperature when annealing plated brass?

You can use a crayon. 600 to 700* the problem is two different metals. If you get too hot the brass will be soft and will not grip the bullet the nickel if it is too cold will likely flake.
I hold the case in my hand and heat the neck just enough to see The nickel slightly change color (You do Not want to see orange or red) then drop it in cold water. I heat about 1/2 to 2/3rd. of the neck, to about a 4 count. Trial and error.
Do small batch maybe 5 or 10 sometime reloading is tinkering and experimenting.

Yes, at least with inductive annealing. The nickel will heat much faster. If you use the same setup on a plated case it will probably melt. So a lower power for a longer time is required. It's a bit more difficult to achieve consistent results with plated cases.
