Hi, it’s normal this? Just some days ago it was working fine.
We’re using TinyMCE Advanced, but doesn’t works neither on Classic editor.

We didn’t touched anything on settings of WPB Page Builder, “products” are active on custom
WP 5.5 (we have forced updates by Siteground, unfortunately…)
We didn’t installed Elementor Editor, to avoid issues and overlapping between editors for our staff.
Thanks
Diego
