BTW on ios if you minimize a pwa it immediately stops running.
NostrSync will be a PWA version of my 'Nostr Backup service," designed to run in the background.
Once you turn it into a PWA, press the "backup & broadcast" button, and minimize it.
This will fetch, download, and broadcast your data in the background. All of this happens without the need for a server.

Is it also happening with this, it is working on background in my iPhone and iPad. Btw ios overall is very bad for PWA, I tried to mitigate that with service workers but still. 🤷♂️
