Toolboxes created in ArcGIS Pro cannot be saved for compatibility in 10.5/10.6 (or below). It just saves a new toolbox with the same ArcGIS Pro compatibility, which cannot be opened on 10.x. Any ideas what I could be doing wrong? Creating a new toolbox from 10.5 would be time consuming. Thanks!
It doesn't work. I think the latest update messed up the "save as" compatibility with 10.x. it was working fine a couple of weeks ago. Now for some reason the "save as" option just creates a copy of your toolbox without backwards compatibility.
Thanks for the fast answer and the reference! I didn't find this one when searching in the known bugs.
I'll see if I can use the alternate solution and report the bug regardless as this was reported for Pro 2.2 instead of 2.6 I've been using.
