I have had a complaint from a customer that they were not able to get their 5AS into learning mode to code in fobs.
This morning I replicated the issue "on the bench" and I can confirm that currently the feature is not reliable.
I was able to occasionally get into learning mode by trying repeatedly, so if anyone urgently needs to code fobs into a 5AS it maybe be worth trying over and over until it works.
I will figure out what the problem is and release an update once it's solved.
