Long lag when using Chrome extension

Hi Dave, thank you for your response!

To answer:
1. Doing some testing this morning, I see this happening in multiple profiles, not just one. The experience is not uniform - sometimes the lag is 5-10 seconds, sometimes 30-60 seconds, sometimes the 1PW extension dialog never opens and I have to launch the app itself.
2. I tried disabling all other extensions - each profile tends to have its own unique extensions, I tried this with all of them - and noticed no improvement.
3. I tried clearing history/cache as explained in the link you provided, again no improvement.

Thanks!
