Student or Learner
I'd like to learn if 'share on network' is a correct phrase as in 'sharing on social network' (in vs. on), I know 'share on instagram' is used.
The preposition is correct but I would say that we share something "on a social network" or "on social networks". I certainly say that I am going to share something "on Facebook".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
