Zoho Desk slow

Zoho Desk slow

Zoho Desk used to run fine in Chrome for me (Windows 10). I had no problems. About 2 weeks ago, it slowed down noticeably. There is a significant delay when I type and then see what I typed. When I click a button, it can take a long time to respond (up to half a minute). Before, this used to be instant. 
I tried opening Desk in Edge but not much better there. My co-worker indicated she has no problem, so I wonder if there is a setting that was changed or something else I can check in my configuration. This issue has made using Desk very tedious and painstakingly slow. 
Thanks!
