Just started getting an error code: an exclamation point within a circle (!) displaying just to the left of my power bars on my center display ( 2018 EVO Street e-bike). It only displays when brakes are being applied. I really don't think anything is wrong but don't know why it's suddenly there. Or how to get it to reset. Cycling power on the display does not change it. Anybody know anything about this? Any advice? Thanks.
