iOS 26 has been officially released, but we recommend holding off on updating until some Safari issues are addressed. These are visual issues that cause fixed position elements on iPhones and iPads to be misplaced after opening the on-screen keyboard — in Discourse this includes the header, mobile footer, composer, and chat.
We're keeping a close eye on this bug and are attempting to build some workarounds in the meantime, but solutions are fairly limited due to the nature of the problem being tied to how Safari calculates the window height (which websites have no direct control over).
These issues appear to impact all websites with fixed elements and inputs.
If you're interested in more details there's a bug report filed with the webkit team here: https://bugs.webkit.org/show_bug.cgi?id=297779
There are additional details and reports on Apple's developer forums and on Stackoverflow.
We can't provide a timeline for when these issues will be addressed, but we'll keep this topic updated as we learn more.
Discuss this on our forum.
