Bias Amp 2 Professional to Elite upgrade

  • I have Bias Amp Pro 2 Professional, when I click on the in app Store button(top right hand corner) it gives me the option to upgade to Elite for £10
    This then takes me to my Positive Grid account page but then the upgrade is now £30 in the basket.
    What goes on here !! could other Amp Pro 2 users please try this.

    Thanks Brian
