I have an old bath top mixer that had a divert to shower
by pulling a ring around the shower pipe, then an automatic
reset when taps turned off. This morning I switched to shower
and it will not go back - I have so far failed to find the right keywords
to start on what I am looking for - any suggestions?

Descale and check the device that *makes* it return

Thanks for that - looks like the descaler fixed it.
