At this point I am starting to see that you guys are either not reading what is being said or you are clueless. 

To point this out for another time, the problem is not from our end, this means that: 

RAM is great 

Operating System is fully up to date

Internet connectivity  is great based on speed tests

Our browsers are up to date 

The issue is clearly from your end, and with the poor support over the years from Quickbooks I am starting to think that we Accountants need to start directing our clients to other platforms.

When will this be fixed?
