How can I share a category with other users?

Highlight (with a long press) the desired category. 

If you need, select other categories for sending. 

After that, click on the icon in the upper right corner with the three dots. 

From the drop-down list, select “Send categories”.

You can send categories via messenger or email.

Pay attention, that the person, who gets that categories, will not be able to simply open the file (as the file has a special format “.lxf”). Instead of that, he/she needs to save the file on the phone and then import it using the “Import” menu item.
