Seems you did receive one reward:

Comment payout for https://hivel.ink/@poshtoken/re-arc7icwolf-the-cheapest-way-to-convert-your-splinterlands-cre-1865

so it should be working unless you've voted the comments yourself which we send to @hive.fund as we don't think it's appropriate to reward yourself with Hive for sharing posts on Twitter, similar to some who go around self-voting all their comments.
