Do ANY Intuit staff monitor & respond to Product Issues. I too have the Win 10 TurboTax 2019 "Updater and Installing Product Update" hangs, then stopped working issues. I did call Online Support and they had me do "manual update" Applying of Updates and Installation of TurboTax program, Federal & State updates is fundamental to the Product. What the Heck Intuit?? Do you monitor Issues w/Software and is there a Bug Filed and being worked?!
