Hi.
I'm facing the following issue when trying to use FOS Notifications (Plug-in) in Apex 23.1:
I have created a fresh new App, import the FOS Notifications Plug-in, and when I use it the message appears in an extra sized box and out of alignment.

But if I import the FOS Plug-ins App 22.1 (the latest release) in the same workspace in Apex 23.1, the message appears with the right (usual) dimensions when using the same Notifications Plug-in.

I have already checked both Apps properties and Plug-in CSS files and are the same.
Any idea?
Thanks in advance.
