This is an IOS issue, not a Steam issue. I have found that no logins work regardless of which one you try to use. Googling brings up a history of this happening. I believe this is likely a Safari issue. Opening up all permissions, enabling Javascript, closing any and all content blockers, allowing cookies, etc. makes no difference. This is on a current model iPhone wil IOS up to date. Again, though, Googling the problem shows a history of this happening with IOS devices. The fact that the APP is forcing login on Safari instead of allowing the use of the users default browser of Chrome or Firefox for example is likely contributing to this issue. Cross browser support can be tricky. I can understand Bungie not supporting evryone and everything. At the least though they should be supporting all major browsers on the iPhone. At the very least Safari, Chrome, and Firefox. Or, better yet, simply allow us to login directly through the app (or via some kind of SMS token we can setup in our account via PC). Back on topic: Do you have any updates or support to provide on this Bungie?
