Hi @ryanewtaylor, thanks for reporting a bug.

The error shows up when trying to drill back and show the zoom reset button which doesn't exist because was (probably) destroyed when the drill back button was shown.

@raf18seb , do you know when this bug may be scheduled for a fix. This is preventing us from migrating from v8 to v9. We are currently licensed for v9.

@ryanewtaylor Thank you for bumping this up, we will discuss this ticket and prioritize if possible. We'll provide more info soon.

I see this has been fixed, but I do not see it included in the release notes here: https://www.highcharts.com/blog/changelog/. Has this fix been incorporated into a public release?

Hi @ryanewtaylor,

we released a v9.3.3 version with one hotfix only. The next version (including the above fix and all other changes) will be released as v10 within 1-2 weeks.
