Ways to improve raid lag?

I updated my game to last version 0.73.1 for android and today I noticed I enter the raid battle 3-4 seconds faster and fought with too little lag. Past couple days I was unable to log into game because of network errors.
Another thing is selecting mons was a pain before the update but today my phone was running so smooth.

Ive had this issue to. I can do machamp but tried a vape with these guys and a dt/o dragonite (instead of the venasaur) and wasn't even close. From what i have read they should have murdered it.

"Is there anything I can do to fix gym lag?" It cannot hurt to close PoGo, power off and restart your phone, and then restart PoGo. This is tedious, but seems to help some of the time. Other than doing the foregoing, I think it is beyond your control, but extremely frustrating nonetheless.

If you're up to date with 0.73.1, all you can really do is follow Barry Dale's advice. If you're still on 0.71.1, update ASAP. When I was on that version my usefulness in raids was effectively halved due to monstrous lag, and nothing helped, had to downgrade back to 0.69.1.
