Point of Sale not working for other languages than English

Hello

We have strange problem with POS not working for other languages than en (English)
Everything works with English but as soon as logged in user language is not English
POS browser session is “grayed out”
Tested on latest v13 and v14 with same result

Any suggestions what the problem is ?

After some testing what works is that POS is working when logged in user language is set to “en”
For all other languages POS page is greyed out and local browser language preferences is applied over user language settings in ERPNext

Hope this can narrow it down
