Stupid question I know, but Google isn't helping and I can't find the relevant settings to change. I accidentally set my Dropbox HTML files to always open in the Samsung Android native HTML Viewer and got a popup saying to go into Dropbox settings if I wished to change it in the future. I want to ALWAYS have the option to choose which app to use to open a file ("just once"), not set a default. But toggling the Dropbox default setting on and off does nothing, it still opens in HTML Viewer. Google says it's the HTML Viewer defaults I must change. But HTML Viewer doesn't appear in my list of apps. And Google suggests to make system apps visible but there's no such setting in my apps. (Google ALSO says there's "no such thing" as an HTML Viewer as it's part of a hidden system package, so, Google is pretty useless now.)
This is driving me crazy, I know I've reset defaults on previous devices. Now there's no option to and I don't even know if it's Dropbox or the hidden HTML Viewer I need to reset. How do I do this now?
EDIT, this is even more urgent than I thought, as I edit all my files through Dropbox and now I can't do so! 😭
