If you look up metadata on the frontend, it runs the grabber as a 
process on the frontend. Android cannot run executables this way, so it 
is not possible to do the frontend lookups that way. For videos, I 
suggest going to setup->Media Settings->Videos Settings->Metadata 
Settings->Perform metadata update after video scan. After adding video 
files on the backend, run
mythutil --scanvideos
on the backend and it will look up metadata for the files you added, as 
long as they have filenames that contain the series and subtitle or 
season and episode. I use Series name for the directory and in there 
file names called for example "S01E01 subtitle.mkv".

The metadata sources in the frontend are list boxes. In V31 there is 
only one option for Movie metadata and three options for Television 
metadata. You should be able to change them using left and right arrow. 
If you are not seeing them you may need to upgrade the frontend and 
backend as there were changes to the metadata update on v31 in February, 
April and May of 2021.
