I have contacted their support team, they will have a mobile version available soon and the languages will be open. If you add a language not English but any other in the address bar, then you will have an error.
Are you trying to get answers from the community or do you want to defend them? There is a lot of smoke and suspicious things about it so it is best to avoid it, you do not have to use it.
There are two important things of any exhange: liquidity and security. There cannot be enough liquidity in a platform that was created two months ago, at least they did not have enough money for a good promotional campaign.
As for security, finding an apparent bug is evidence of weakness or lack of updating from the team, so it is better to avoid them.
