I've been using ZorinOS for about 2 weeks and I've found an annoying problem. It's generally very good other than this.
I use it as my work PC and we use Slack and Zoom. I've noticed that for example in Slack if you go to upload a file, much the home directory is hidden. For example, my "develop" directory does not show. It only shows Documents, Downloads, Music, Pictures and Videos and no other folders. I tried the "+ Other locations" option but develop is hidden as well as other folders.
In Zoom, I tried to add a background image but had a similar problem. In fact, no jpg files could be found. It's like the dialog box is crippled. The normal directory browser shows everything. Where is the magic setting that turns off this broken functionality?
