Done ALL that but is seemingly getting slower and slower every day, each simple transaction (just entering) takes many seconds... My PC is up to date, I have not changed my browser since I started using QuickBooks (2019), ALL my other online programs are fast.

QuickBooks seem to be cutting back, is this just more of the same,lowering speeds to save $$ 

The new CORE Payroll is also a mess, it has lost all my timesheet data...More cutbacks.
