Target SDK doesn't support runtime permissions but the old target SDK 23 does

I am building a VR project which I have built before successfully but am now getting this error message “Target SDK doesn’t support runtime permissions but the old target SDK 23 does”. What did I change? Nothing to the project itself, the only thing that is different is that I installed Unity 5.6 in a separate directory. This build was done in 5.5.

My question is - I assume they are referring to Android so where do I change this? If It doesn’t like 22, how do I change it to 23?

I had the same problems and I solved them deleting the app from the mobile and the computer, and building again using Build and run (Ctrl+B)

Totally solved the problem for me. Good luck.
