Hi Daniel,

Thanks again for reaching out and flagging the regression. The level of detail you included made it much easier for us to track down the root cause.

I’m happy to let you know that the issues have been resolved. The fixes are scheduled to go out with our upcoming 2026 Q3 release.

We appreciate your help in keeping things running smoothly.

Regards,
