Something changed between PS versions. I do have module in PS 8.1.3, where it works. Now, I´ve installed on PS 8.2.2 - admin part seems to work, front shows new payment option, price addition in payment option text, but no fee listing in right column and no added price to total.

I do not have 500 on ajax call tho.. It´s normal 200 OK, but nothing changes.

Sadly, the module is sooo large that I have no clue what to search for...
