When working at home, using only wifi with a booster on a national carrier and MacOS Mojave version 10.14.6, Indesign 2019 (14.0.3 and using Adobe Cloud) does not allow access to styles panel to edit or do anything with styles. When working in-office and using wifi there, I have no problem accessing the styles. At home, Indesign just does nothing forever and I have to hit ESC to go on to do other work, not getting the changes I need.
