I've found the issue is still present. A workaround is to use a ZStack to overlay two charts with identical scales and axes. The first chart (background) is non-scrollable, allowing us to draw the selection RuleMark and an annotation popover. The second chart (foreground) is scrollable and enables data drawing and selection.

Just to add additional information, the server from where I'm trying to make the connection has the following versions: curl 7.85.0 (x86_64-redhat-linux-gnu) libcurl/7.85.0 OpenSSL/3.0.8

I've been struggling with a similar issue that makes the app crash using either Form or List. In this case I want to conditionally show the picker based on a previous option in the form. It shows the picker, but after a couple of selections in it, it crashes showing no detailed information on the error. It also in IOS15 and Xcode 13, testing directly in an iPhone 12 Pro. Didn't find a solution yet...
