I’m glad you consulted a real expert - the Grandkids, lol.
Coincidentally, I had ordered a new IPad and it arrived yesterday. And yes, both frames scroll on the new device. So, it’s time to say a few words over the old one and send it on to IPad heaven. At least now I have an explanation for my website viewers that have problems with scrolling frames. Thanks to all for the assistance in this matter - especially the Granddaughter.
Stay well.
