Yes I have had many cases about this and have been connected via our CSR and directly calling in myself. I have done the screen share. The list you attached is one of the list customer support did run through with us and we have tried all of those fixes on the list.  I am really looking for recommendations other than what I have tried from the community. Hoping someone has ran across this before. I have read lots of blogs, and post about this issue and people being frustrated for the same reason we are ............. the fixes are not working and the new roll outs doesn't fix previous issues.
