> Are you saying the Safari browser on iOS intentionally cripples web applications by randomly erasing / deleting browser data (cookies, localStorage, etc)?
I would absolutely make this claim.
This isn't even a PWA thing. We had a really simple series of boring web forms that suffered from this. The first iteration of this had the server swap an initial tokenized link for a cookie when clicked.
After some feedback from our customers, we discovered that iOS users were having a lot of trouble getting all the way through the desired workflow. We were able to replicate this on our iOS devices but it seemed completely arbitrary.
After abandoning cookies in favor of maintaining a tokenized URL, we found we were getting 100% success rate for iOS end users.
My theory is there is a malicious bit of code in iOS Safari that is applying some insane cookie policy over "unpopular" domains.
I think they have a thing now where all stored data gets wiped every few days (in the name of privacy, purportedly). And yes, that broke a bunch of apps.
