Dima,
I really still hope that you are joking:)). Open any good website with filters and you will see that pressing back keeps all marked filters.
By the way, in your filter when you go back, ALL CHOSEN OPTIONS REMAIN MARKED, but in fact they don’t work. Or it is also a special feature?:)))
Is there any possibility to fix this issue?
Normal user experience is that – you just open a product page, look at it and press back.
As we like your filter we would appreciate a lot if you could help with that. Thanks!
