Web Push on Safari on iOS (works fine on desktop) https://onesignal.com/blog/the-state-of-ios-web-push-in-2020...

Safari on iOS deletes LocalStorage after 7 days of inactivity (https://webkit.org/blog/10218/full-third-party-cookie-blocki...)

The 7 day limit does not apply in any meaningful way to PWAs. From your link:

> As mentioned, the seven-day cap on script-writable storage is gated on “after seven days of Safari use without user interaction on the site.” That is the case in Safari. Web applications added to the home screen are not part of Safari and thus have their own counter of days of use. Their days of use will match actual use of the web application which resets the timer. We do not expect the first-party in such a web application to have its website data deleted.

> If your web application does experience website data deletion, please let us know since we would consider it a serious bug. It is not the intention of Intelligent Tracking Prevention to delete website data for first parties in web applications.
