Thanks, I appreciate all this but I haven’t a clue exactly how to adjust these things? Whenever I tried I just made it worse and even worse couldn’t even get it back to where it was before! (on a previous bike).
At that point I decided that repairs and adjustments were out of bounds without first learning how to do it properly, preferably by being shown rather than just reading it.
You don't do anything drastic. Just a quarter turn on the barrel adjuster. If it makes it worse turn it a quarter turn back. You'll see the mech move nearer or further away from the sprocket as you do it. It's not rocket science.
Same with truing wheels. It's very easy.
