I just installed QB Desktop 2021 and sure enough, IE 11 is still required.  This thread, or others like it are predominate in this forum.  I find it ridiculous that a "software team" that is supposed to design applications to customer requirements, and provide appropriate security cannot make the simple design change to allow another browser rather than an obsolete, unsecure browser.  In today's world where big companies are being hacked, unsecure software is the primary target.

Intuit, get out of the rut you have been in for years and allow any browser.  In the meantime, while I wait, I'll download my multiple bank accounts manually.   Perhaps, Intuit should be refunding me for my time doing the work the software should be doing.
