Hi Steve,
Thank you for taking the time to give me a thorough run through of what to do. Apologies for the late reply.
The first fix is done (removing the 2nd piece of script for the model viewer), and I have had a play around with the other vendor elements. I have tried out removing #Responsive Iframes, #Lazyframe and #Plyr as suggested (the site doesn’t use video). My knowledge of code is VERY rudimentary, so I didn’t have too much luck. I am going to have another try of it in the next few weeks. I will let you know if I’m successful.
Thanks again,
Steven
