Downloads progress is not accurate on the Dynamic Island

[chickenwaddle77]

Steps to reproduce

1. Download a file
2. Exit Firefox app
3. Note the progress on dynamic island
4. Swipe up and note progress on notification centre
5. Check progress on dynamic island again
6. Wait some time and notice that the progress on dynamic island does not change

Expected behavior

Notification centre progress should be in sync with dynamic island progress

Actual behavior

Notification centre progress is always more in sync with actual download progress than dynamic island or dynamic island does not sync with download progress at all.

Thanks @chickenwaddle77, this has all the info we need! 👍 Can you please make sure your shared "actual behaviour" file is publicly visible (I can't see it), or upload the clip directly to GitHub here if possible? Thanks! 😄

Hi @lmarceau, I would like for this to be assigned to me. I noticed the following logged to the console when I closed/minimized the app while downloading a file. It seems like download is suspended until the app is brought back to the foreground

Hi Isabella, so sorry for the long break 😭 I was a bit busy with school/work and completely forgot about it. I wondering if I can still continue off from the same tickets and I'd love to continue contributing! I messaged you earlier last week on Element but I'm assuming you're on vacation. Thank you so much!

Hi @BlessedOneKobo, @chickenwaddle77 originally reported and was assigned this ticket so let's give him another shot at resolving. But if you are both open to collaborating, feel free to discuss any findings here in this ticket thread. 🙏 It would not surprise me at all that Apple suspends or throttles downloads while the app is backgrounded (as we've noticed with Live Activity updates in general). There should be a way to handle this as Safari is able to update its download Live Activities consistently.
