Collabora Online Development Edition Spreadsheets

Hello everyone,

After upgrading Collabora Online Development Edition from 4.2 to 6.4, I need to print spreadsheets files with landscape layout, But I can’t find this option, Also I need to print selection (when selecting multiple cells).

Also I created a new topic in https://forum.collaboraonline.com, they told me that I need to follow these instructions to Switch Collabora Online Notebook Bar to Classic Tool Bar.

How to apply these instructions in UCS platform?

I’m using Nextcloud 19.0.4 + Collabora Online Development Edition (CODE) 6.4.0 Appliance
