First of all, this is an excellent platform, and I am unable to fault its variety of rides and training. On the negative side, it's quite expensive, and my main problem is the customer service regarding reporting rides that are not recorded. Normally, I wouldn't have bothered; however, this was an over 100k ride. Luckily, I had the photographic proof. I haven't heard back from them, and this was reported back in December 2024.
So come on Zwift, sort it out!!
P.S. Not an internet problem.
