QB is running extremely slow

Hi MT, thanks for posting on the Community today

We're aware of latency issues that mean some QuickBooks users are currently unable to complete any tasks. 

This has been escalated to our formal incident team who're working on resolving the issue with priority. 

We appreciate your patience in the meantime and apologise for the inconvenience caused. We'll be around if you have any further queries. 

Has this issue been resolved as QB online runs ok for 10 minutes then all the dropdowns for product/service and vat selection, when creating an invoice, just freeze and its impossible to continue, or even save the invoice to return to after restarting the browser.   

Windows is up to date, browser is up to date, and there is plenty of ram.  i dont experience this problem with any other web site so can only conclude its something to do with QB.   

its becoming very frustrating as we need to issue many invoices and its not really possible without wasting a lot of time re-inputting data after the dropdowns freeze.
