Google Analytics Bounce Rate is high since moving to WPMU Hosting

Not sure if you have an answer, but since we moved our hosting from GoDaddy to WPMU, our site has functioned great, but it seems that our numbers are way down in terms of traffic. A recent look at Google Analytics is showing massively high bounce rates, which we didn’t have on our GoDaddy Hosting. Are we running a function in our multi-site domains that is causing this? Since July 5, our bounce rates have been in the 80%range with some days as high as 100%. On one of our sites, we have a 19,686.60% increase in Bounce Rates year over year compared to 2018. All of these increases began on July 5, 2019 which is when we moved over to WPMU. There mus be some sort of correlation. Please advise.
