Online User Manual
The question I have is - which specific version of the app is this manual for? There is no version number on either the title page, nor as far as I can see anywhere else in the document. I suspect that it is for v2.x of this app as the copyright notice on the last page refers to 1992-2020, although the address of the web page refers to v1.0.
Since v3.0 of this app is now available - I downloaded it from the Paly Store last week - and its now May 2021 can you ask the writers of the manual to at least include the main version number of the app which it relates to in order to avoid confusion? It would also be very helpfui if the actual publication date of the document could be included so that everyone could tell whether they had the latest version.
