2 problems with my e ride wondering if yall got any fixes or nah

so first and lowkey the bigger problem is that after like 5km of riding my e ride shows the error 00300 while trying to reverse and i have to turn the bike off and on for it to work again
and second idk why but my e ride pro app shows my 3.0 l1e as a 2.0 offroad and i dont have alot of the functions in the app (atleast i think so) such as the speed limiter (i only can set the power in %) and the app looks older idk if i have to update it somehow but i uninstalled it like 3 times now. any help or tips idk?
