At https://help.dropbox.com/installs/upgrade-latest-version under "How to see which version of Dropbox you're running" it says version can be found in Preferences "at the bottom of the dialog box (underneath Language)". Not for me, it can't! All that shows below 'Language' is 'Show Dropbox Badge', with 3 options in drop-down list, and 'Show Dropbox in Microsoft Office as a save location' with an 'on/off' switch (it's on). Where DO I find current version?
I should add that CCleaner tells me my version is 200.4.7134 and it also tells me that the current version is 202.4.5551. Dropbox tells me the app is autoupdated which, according to CCleaner hasn't happened. Can't find any way of manually updating that works. I'm running fully up-to-date Windows 10.
