A long time user of Wings platform who started forecasting shortly after the Stox forecast was complaining on telegram how he has never received a single reward.
Apparently he thought rewards just showed up in your wallet.
Just to make it clear, All rewards have to be manually claimed, even it beta, although in beta rewards will become available immediately after the sale ends, if they used the Wings Constructor, If they use a custom contract you will need to verify that the contract will pay a reward, and if not you'll need to flag it.
A few other points some people are just now realizing, in beta you can forecast on any and all projects with all of your Wings and there is no need to unlock them from one forecast to forecast on another project.
This is actualy useful info especially for those that bought WINGS on exchanges, is there a guide on how to claim rewards or how to see if your forecast actually earned rewards?
You have to predict close to what a project will raise, The closer you are the better rewards. If a reward contract is deployed you can go to alpha Wings version and claim your rewards.
I have been maintaining a list of projects for which rewards have been paid also other information, You can go check here..
