Is it me, or did SD (at least on my iPad) used to show the limits of parachute DZ's with a circle similar to (but not the same as) a ATZ - and now doesn't?

Same applies to glider sites - there's just a glider symbol shown on the chart with no depiction of the limits of the "launch zone" - and I thought there was.

I get rather nervous about these "sporting areas" & obviously want to avoid for safety reasons, especially as radio contact can be "intermittent" - but at the same time I want to ensure my routes are as efficient as possible. & not give an unnecessarily wide berth.
