Rank not changing after winning games

I’ve won the last two ranked games but my rating has not changed. Is this an issue or were these not ranked games?

Your opponents “Timcour” and “Platybelodon” are/were of provisional ranks. Playing against provisional ranked players won’t affect your ranking.

Thank you, that helps. How can you tell if a player is provisionally rated?

Just going to his profile page. If he/she’s provisional, you’ll see a text like:

Note: This account is currently marked as provisional until 2 more games have been played
