I'm not able to log in since the log in pop up window always hangs. This is on Mac OS Tahoe 26.3 I'm forced to use SDK version 8.4.0 to view crash reports.

Please consider improving the compiler by doing the constant folding earlier, so we can use code that is guarded by a constant: (:no_foo) const FOO = false; (:foo) const FOO = true; class Foo { (:foo) private var fooOnly as Boolean?; function foo...

It seems that SDK 9.1 introduced changes to how the simulator handles JSON size limits. The release notes state: “Enforce max JSON response size limit for BLE web request.” However, it now appears that the limits enforced by the simulator are lower...

This has been discussed in the forum, but we haven't heard anything about it since. It's still happening to ma multiple times a day, especially when I have long walks (more than 30 minutes). It can happen multiple times in the same activity (when I see...

Use case: I'm developing a slope/inclinometer data field that displays real-time pitch and roll angles during an activity. This requires high-frequency accelerometer readings to provide responsive, accurate tilt measurements. Data fields are the natural...

I have a valid SVG icon I want to show in a Edge Datafield, but rotated -90 degrees. So I added transform="(rotate,-90)" to the svg. The resource compiler ignores this. The icon shows correctly rotated in a web browser, in a SVG editor and in VSCode...
