Terms store columns and mobile apps

I can't seem to do anything with columns which uses the Sharepoint Terms Store in both the new "Microsoft Lists" app and SHarepoint App on IOS.

Is it really true that "terms store" columns are unsupported in their own apps?!? This seems incredible stupid to me in a mobile first age of internet. It makes the term store completely useless. I can't imagine anyone who only ever manipulates sharepoint lists on a PC.

Please tell me i'm wrong on this!!
