Summary

I've been trying to get BackgroundFetch and Background Notifications to work on my iphone. I am not able to succeeded, i've tried doing research but on both the forum and discord i've only found ignored or unresolved issue relating to this matter.

I made another issue a few days ago but it was related to expo-router, but now i think it may just be broken? #29792

This is a duplicate of #29558 , and judging from the version of expo you have, that holds

I've been trying all day to get remote-notifications to work, i'm not sure what next steps to take at this point

Update: left it running all night again and for the 3rd night it rose!.

I'm guessing iOS does a lot of throttling with background tasks even cause by push notifications?
