One of my colleagues created a Wikimedia account especially to contribute to ISA. After having created the new, fresh account, she logs in ito ISA, allows the OAuth screen, goes to an ISA campaign, add a Wikidata-tag... now she wants to save her contribution, but that does not work
This might be intended behaviour (perhaps new users must first have made a certain treshhold number of contribs??), but in that case that should be cleary communicated in the ISA tool itself
