Hi, I set up my new MBP 2018 i9/32GB yesterday and I am loving it so far except for one issue. I use external bluetooth keyboard and trackball, and I have noticed that, randomly, both devices end up lagging. I would say that this happens about once an hour. I had these exact same devices connected through bluetooth on a 2016 MBP (now unpaired) and didn't see any issues. Any ideas on what might be going on here? Thanks!
