JakubDre_l With respect, you can’t guarantee that. I work in technical support for another company and if I had a dime for every time someone said “It’s definitely this problem!” and it turns out to be something else, I would be a wealthy man. Similarly, “this firmware update broke this feature!” and invariably it’s something else.
You may be right! But, you might not.
So, you’ve talked to technical support, yes?
