Sorry for late response and thanks for your thoughts.
No, not as yet. I’ve not brewed for some weeks for obvious reasons though my friend has. He’s having the same problems as we’ve experienced before. My hunch is that the temp probe on the ‘all in one’ system isn’t registering the mash temp correctly, so the more fermentable ‘spectrum of sugars’ are being compromised. As I think I said, this problem did not arise when we brewed with our Tower system.
Should be back brewing again soon so see what happens.
