It’s fine to reboot whenever needed, but since you charged to 90%, if it was below or even near 60 degrees where you are at, and the car was cold-soaked to that temperature, you would expect to see this message, along with a lot of dots on the left hand side of the regen/power bar. It’s totally normal.
Park your car in an attached garage if you want to reduce the occurrence rate. Summer is coming though so should be fine until fall.
