Hi, please let us know how you managed it.
I’ve bought tickets for me and my son (Kingsland @ £45 each), but at no point did I see a switch/button that would have enabled me to use one of the ‘Plus’ tickets. I’m not doubting you, would just like to know for future reference (and to help others in a similar position).
Indeed if anyone has been successful with this issue, pls post a screen shot of the relevant screen.
Thanks
