In stressful times it’s easy to loose the overview over requested Pull Request reviews. Luckily, GitHub provides an easy way to list all the PRs where you are an requested reviewer:
Just go to https://github.com/pulls and filter for is:open is:pr review-requested:@me, or just use this link:
https://github.com/pulls?q=is%3Aopen+is%3Apr+review-requested%3A%40me
Voilà! There you have a list of all review requests, even across multiple code repositories. Similarly, you can list all the Pull Requests that are assigned to you.
