After 3.8.0 update I no longer have an option for external themes in vector maps. From Main menu > settings>map advanced>Vector Maps> Map themes I only have Internal themes option. No longer is there external themes option or more option. I have researched the user manual with no help for external themes.
using Samsung Note4, v4.4.4 ( tho new version is prompting me continually to upgrade).
I suspect the problem lies in the directory structure. But all worked fine in prior Locus Pro ver...just lost it on3.8 upgrade.

Did you try to tap on "More" in internal themes?
