Delayed motion/sound notifications

Ever since I upgraded my camera and phone to the latest firmware I haven’t been getting reliable notifications when my camera senses motion and or sound. Some of the notifications work while others seen to have a 10+ minute delay. Once I go into the Wyze app a bunch of notifications popup. Last night I was walking around right in front of my camera and I didn’t receive a single notification. Any suggestions on how I could attempt to resolve this issue?
