Mobile app is awfull

How did such awfulness as TfT mobile app (android in particular, if this matters) bece acceptable?

There is no: - ability to change language in app to English. I have to change what then? System language? Google play language? - no built in wiki/knowledge base/basic info on stats, items, comps, heroes, abbreviations. - user experience in game is pain: autoopenning store page resets any selection made before, it's impossible to tap on inner items in popups etc. - interface is just so tiny, with no option to scale up.

Is it because mobile is not target audience? Is game PC-first?

Coming from Autochess (mobile legends one) this one is such a bummer.
