Can Schengen visa from France be used later on for other countries as well with a break? [duplicate]

  • Does a multiple-entry Schengen visa allow visiting other Schengen countries later, without going via the issuing country? 2 answers

I want to apply for a Schengen short stay Visa for France to travel in August 2019. The duration of the stay will be for 3 days and then I will return back to London. Later on, can I use the same visa to travel for a longer duration to other Schengen countries and return?

Also, as far as I understand from this forum, once I get the visa issued from France this month, I cannot use it to travel to another country for two days and return to London before going to France in August.

Correct me if I am wrong.
