Raids and Gym freezes

I dont understand why there are so many bugs, it worked really well for me the first week of the update. Since then its frozen is 4 out of every 5 raids I try. Im furious at the waste of my raid passes. Im to the point where its more infuriating than fun. Enjoyed the raids but I will no longer be participating.

My other complaint is the gyms wont let me battle the full set. It boots me out when I get to the second Pokémon. The whole thing is frustrating and makes me want to stop playing all together.

Super f happy about Pokémon GO, v1.37.2
