Having iOS OBD11 coding issue. Never had this happen before on my old car. New car is a 2016 Golf R. In central electronics after I enter security code 31347 I get the success message, but when I try to change adaptation values I get the "function not available". Sometimes it'll let me change one or two values (ie change value, write, change value, write), but then stop working after like 2 or 3 with a function not available message. If I tried to do a few at once, it never worked.

Edit: Just in case anyone runs into this problem, the solution was to get an Android phone or tablet and do the coding that way. The iPhone/iOS OBDEleven app has been nothing but problems. Grabbed a cheap android Samsung galaxy phone and I was able to do all the coding without any issues in one go.
