I’ve enabled Experimental Features, and am trying to use Data–>XML Source… to work with XML data. At the top of the window, under Source File, is a button beside which it says “not set”. When I click the button (to choose the source file), there is a delay of a few seconds after which I get a spinning rainbow for about 15 seconds, and then nothing happens. There doesn’t seem to be a way to select a source file.
LO 7.3.2.2, MacOS Catalina.
EDIT: Turns out the problem is a more broad than initially described. With “Allow Experimental Features” enabled, browsing the system for a file doesn’t work in general. For example, Sheet–>Link to External Data, the Browse button has the same problem, spinning wheel then nothing. That’s not an “experimental feature”, and if I disable “Allow Experimental Features”, that same Browse button works as expected. Even File–>Open doesn’t work with experimental features enabled.
