I tried starting a couple of rides recently and the scooters wouldn't accelerate. According to the app and readout on the scooter they had plenty of battery and the app didn't indicate i was in a slow zone. They simply wouldn't accelerate after unlocking. On one of the rides there were additional connectivity issues trying to actually end the ride, which didn't make sense as I was in the middle of a dense urban area with plenty of cell coverage on a variety of characters. Terrible experiences.
