Whenever i open my profile in the iphone app, it freezes. And then i can't open my previous games or statistics. Using iphone 6 plus.
There is same problem with the Firefox browser. In my computer, Lichess works only on Google Chrome. So try Android smart phone. Lichess should work fine there.
The thing is i don't have any android smartphone :(
For best results use a desktop or laptop on the google chrome browser and use the the lichess website, not the app.
