Recently we upgraded ArcPro to 2.6.0 and since then I have had issues with configuring the legend :
Is anyone else experiencing these issues? My work around has been converting to graphics, but that is not ideal.
I'm not aware of any known issue specific to this. There could a number of things happening and without more information about your situation there's little that can be done. Can you contact Esri Support? They are better equipped to handle troubleshooting steps and gather bug data. They can be contacted at https://support.esri.com/en/contact-tech-support.
Hope this helps,
The "only show features in extent" seems to just be happening with one layer in my project. I found a work around for now, but I will put a ticket in with ESRI Support. Thanks for your response.
