@Dunc if it helps (but I’ve written that too many times, so, sorry), here are many useful stuff about how to do something on the forum. They’re explained through browsing it with the PC, that’s true, but since forum doesn’t get its own app, more or less browsing it is the same though any browser of any device. In the same topic you can suggest me what to still put in, what to correct etc. i tried to give graphic explanation for more or less every thing I covered so the instructions shouldn’t be too complicated. And, at the end, you still can ask on here if anything isn’t clear enough.
Happy posting and exploring.
