While Intuit has made some program changes for Lacerte 2019 to use the Edge Chromium browser, it should be noted that many users still do not have the MS Edge CHROMIUM Browser installed.   Unless you regularly use IE 11, then you may not have been offered the update.

Intuit, please indicate, what if any pre or post install actions, are required if the Edge Chromium browser is installed AFTER the 40.0729 update.

Will this fix be ported back to at least 2018?

Indirectly related, the 2020 Lacerte System Requirements defines IE 11 as the required browser.  I expect that this document should be updated

FWIW, I think that most users would prefer to have their "Default" browser used for web content in Lacerte (at least I would).  I can understand that you may need to call Edge for the login, but not sure why for the balance of duties.
