v2 on Windows phone

Hi,
since the v2 update, I cannot play lichess any more on my cell phone, which has Windows Phone 8 installed. There is no lichess Windows app, but until now the internet site got well displayed and worked. Since the update, graphics as chess boards or the cubes for Quick start 2+1 / 3+2 etc. do not get displayed any more. Hence, I cannot start/play any game. Is there any solution, can it be made working for all systems (incl Windows phone), or is there a link to still use the old lichess version? I'm not sure if the forum is the right place, but maybe someone has the same issue.
Thanks

What's your main browser and have you tried a different one just to see if it works there?

My main browser is the explorer, but I've already tried out like 10 others, and for many I get even a message displayed that the browser is too old for the lichess site. For the others, I have the same problem as with the explorer.

Internet Explorer isn't supported, it's outdated, even Microsoft abandoned it several years ago.
Try Firefox or Chrome, but make sure they're latest versions (61 and higher for FF, 60 and higher for Chrome). If they are and it's still not working, then yeah, there's a bug. You should probably show a screenshot then.

..Firefox or Chrome apps/browsers are not available for Windows Phone.

You may not be able to use your Windows phone then as the tech is outdated.

it's time to buy a new phone.
