Live View can lag when opening it

I did have a Nest Doorbell Battery, but got rid of it due to several issues, one being that the Live View lagged when opening it way too many times. So, I bought a Ring Pro 2, and so far it is much better overall. However, it too can have Live View lag, but not as often as the Nest. Also, none of my other 4 cams have ever had this issue ever. The only common denominator is that both violators are Doorbells. I know the most common go to fixes, Wifi, Transformer, etc. but they have both been tested and proven up to the task. I would love to hear from someone who has tackled and hopefully solved this issue. Or at the very least, a viable answer as to why it happens.
