In order to check recently accumulated rewards from your daily focus rewards or season rewards, click on the Details button of your season chests and go to the show last season's rewards link in the window provided to you. Although, this option is only for displaying the previous season's opening.
To view a more expansive history of your rewards for prior seasons, you will need to use a third-party site like Peakmonsters. To view your history, copy and paste the following link, then replace the word "username" within the link (https://peakmonsters.com/@username/explorer) to open up your history on peakmonsters.com.
Shown above is both a daily focus reward claim from about 11 days prior and then the prior season reward displayed on the Peakmonsters website.
You may have to use the filters on the right-hand side of the screen to filter only Rewards cards. Do note that if your history is already expansive with market transactions, you may receive very few results initially displayed on your page. To resolve this issue and view more results, click the spinning arrow icon (circled in green).
This will provide you with more of your past results and populate the Load More Activities button at the bottom of the page, which if clicked, will show more rewards transactions but there are limits to how far back it can search, which can sometimes vary.
This method of checking history is often utilized by users that accidentally skip their chest openings in some way, whether by error or by navigating away from the page to confirm that rewards had been received, and what these rewards were.
This concludes the guide for reviewing your season and daily rewards history.
