Thanks for the PR @cieniawska - I'll review it in the next couple of days.

Hi @cieniawska I reviewed the PR and went ahead and made some changes to it.
Main thing is that I noticed that userId and anonymousId values were not being sent with the track() call.

I opened a new PR to include these changes: #3364

Please take a look and confirm if any additional changes are required to that PR. If they are needed, please raise a PR into that branch (please don't reopen this current PR).

Kind regards,
Joe
