why is screen time glitching?

my parents have given me screen time limits, but they don't work as intended; for some reason, there's multiple glitches. I.E. If I run out of time on an app, when I get granted more time, no matter if I use that app or not, the time is still used. I could use chrome for 40 minutes after I get an extra hour, I can shut off the device for 30 minutes, but I get back to chrome and, although I expect to still have 20 more minutes, it's back to being blocked. and, then, to add insult to injury, recently, I don't even have to close the app for it to run out; I could be doing something on, say, capcut, but I leave chrome open, the latter of which runs out of time, even though I don't use it. now, I'm sure some people will think "why not close it if you don't use it?" it's just a huge pain to get back all the tabs I had. that aside, does anyone have any suggestions on how to fix this?

P.S, this is not exclusive to a single device; it's every. device. I have.
