Question about screen time limits - how much is too much?

Got two kids - 4 and 8. During the pandemic we got pretty relaxed about screens and now honestly we're not sure how to dial it back. They're not glued to devices or anything but like... 2 hours on a Saturday feels normal to us now when I'm pretty sure that's not ideal. Other parents - what does a typical day look like for you guys? Are you strict about it or is this just how it is with kids now?
