19.12.2.1 - Latency Issues - Anyone else noticing slow response times?

Greeting to my fellow Unifiers. 

We recently upgraded to 19.12.2.1 which retires Classic View.  We were aware that Standard View does load a bit slower when initially starting the web app, some caching in the background. 

However, now that all users are fully using Standard View they are reporting that response times are even slower with the new version. And this is from people who were using Standard View prior. 

1.  Are any of you experiencing latency issues, not only during the initialization of the app in the browser, but also when you move to another project and try to access another BP, Cost, Sheet, Document Manager, etc?
