Selective Sync not working, can't sync folders to the app

[ANB]

I just got a new computer (Mac) and when downloading the app it asked me to select folders. I only selected a couple thinking I can update this later. However I can't figure it out. Following the Selective Sync article ( https://help.dropbox.com/sync/selective-sync-overview) it states click on Preferences and then the Sync tab. However nothing happens when I click Preferences, no new window opens...

Hi there @ANB - sorry to hear you're having issues with this.

Could you please clarify your device's exact OS version and the version and status of the Dropbox desktop app as well?

Have you rebooted your computer since you first noticed this by the way?

Let us know more and we'll take it from there.

This issue has now gotten even worse as now Dropbox won't even open, I keep getting an error message saying "Couldn't open dropbox. This may be a temporary error. Please restart dropbox." I've restarted, uninstalled and reinstalled, rebooted the computer and downloaded the latest OS Sanoma etc. But nothing works.. Below is the message I'm getting. I'm using a Macbook air.

Thanks for the update @ANB 

Could you close the Dropbox desktop app, reboot your computer and then relaunch the app anew? 

Let us know if you still get the same error!

[ANB]

Hi, Just tried that again now and it is just showing the same message.

[Walter]

In that case, could you try an advanced reinstall and let us know how it goes @ANB ?

Finally got around to trying this and it worked. Thanks so much for your help!
