Zero support :(

Update 03/30: avoid this app, after one month nothing changed. Video still not work, you always get a play error and youre forced to use alternative player. At that point just stick with the official YouTube app that improved a lot in the last months and in my opinion is now superior (and free).
Still zero support from developer(s), all my email went to the void. Jedi voice: this is not the app youre looking for.
Going to delete it, wasted money. :

Update 02/28: this app is getting worse with time. First comments not showing, now the player getting *always* timeout. Also search field has auto correction enabled, that forces you to correct every single name/foreign term. And still author never answering support requests. Im now looking for a valid alternative. :(

I wrote the authors several times in the last year, to report bugs (like the current one where comments arent shown anymore) and they *never* ever replied back. Not a single time.
Bad support like this is very rare. Avoid this app.. :(
