Seеms that pockettube banned all users with russian language in operating system. developers need to now, that russian language is internetional language for many countries, like Kazakhstan, Armenia, Azerbaijan, Tajikistan, Turkmenia, Kyrgyzstan, even for Georfia, and Ukraine. So banning russian language, you banned a lot of users, that never was related to Russia-Ukraine relationship. If someone says that war in the Ukraine more important than anything, i will say when war was in my country, world went on, and no one did not condemn the agression against my people. Ukraine not special.
Upd. Last usable version for me is 11.0.11. Any above version just dont work. Im not from Russia or Ukraine. And understand your position. But something looks broken.
Upd 2. Thanks, changing country from Russia helps. Unfortunately youtube has no Armenia in country choice, so i was using Russia.
