I would like to know how to revert to the prior version of BD before 2019.  There are too many bugs to continue to use this version.  I am unable to print to my network printer since installing BD 2019.  It works fine if I uninstall BD 2019.  It is a Canon MB2720 and I've tried turning off the BD firewall, no help. Other family members are also having issues.  Need to go back to previous version until this is resolved.
