@jltx Thanks. I have gone back and checked which iOS versions work with which DWC versions, with the iOS devices I have available:
iOS 10.3.3 (iPad 4th Gen) - up to RRF/DWC 3.4.6, blank page with 3.5.1
iPadOS 15.8.4 (iPad Air 2) - up to RRF/DWC 3.5.4, blank page with 3.6.0-rc.2
iPadOS 18.4 (iPad 9th Gen) / iOS 18.4 (iPhone 15) - 3.6.0-rc.2 shows correctly.
I'd guess that your iPad with iOS 12.5.7 would work with RRF 3.5.4, which is the current release. If you could check, that would be helpful.
3.6.0 is still in testing, so it might yet change. @chrishamm says it's the 'browserlist' (https://github.com/Duet3D/DuetWebControl/blob/v3.6-dev/package.json) that sets the browser versions that DWC can use, though this is the same as was in the 3.5 release:
"browserslist": [
"> 1%",
"last 2 versions",
"not dead",
"not ie 11"
]
I'll update the 'Browser compatibility' text on the DWC wiki page.
