Can any1 help me my raid battles doesent work i have lost 3 raid passes becouse there comes and error and it doesent let me battle any1 know what to do

I’ve had the game freeze up on me a few times when I started a raid. Every time I turned my phone off and restarted the game, it still let me continue with the raid. Have you tried turning your phone off when you get the error message and restarting?
