3 Satellites cross overhead and pulse bright white

I was just watching the stars through a 70% cloudy sky, and saw a satellite heading NW of normal brightness moving at normal speed, then it turned really bright for a second, like it was rotating the bright a light mounted on one side, and seemed to roll over the other side in a smooth motion.  Like the light on top of a Lighthouse, spinning around one time (as opposed to a regular lighthouse spinning repeatedly).
It kept travelling at the same speed, and seconds later I saw another satellite coming from a different angle heading south, but the same speed.  Then a third appeared from its own angle going SW, and this one pulsed bright for a second just like the first one, all of them white moving dots.  They all crossed paths within 15 seconds of each other and kept going.  My phone camera couldn't capture the video, the whole event lasted about 90 seconds. Ambaum & 125th St. At 10:46PM 5/19/2020.
