I have had a break of about two years just using an iPad and iPhone as my only computer devices. For many reasons my experiment didn’t work (iOS Files is not quite there yet) and I had the opportunity to get a near new, hardly used, Mac mini M1from my daughter. It’s a slow job, but I am getting everything setup the way I like it and trying to get “the muscle memory” for all my old favourite app working again. Acorn was always one of those apps.
PS: I’m staying with 7.3.2 and “Export (Web & Other)” works fine!
