As I understand it, we upgraded a dependency, but the new version relies on certain methods that aren’t available in some browser contexts. The fix is to use something called a polyfill; a scripted method to deliver the same result even if the “native” method isn’t available on a particular browser.

The release note item calls out iOS, but we’ve seen reports of issues on other systems: [Nightly 8.1 Changelogs - 2021 - #94 by sreis](http://forum.inductiveautomation.com/t/nightly-8-1-changelogs-2021/42410/94)

Projected release of 8.1.8 final is early August.
