Additional info

Btw: printing is not very convinient. It's missing date and time of the message and often does unnessesary pagebreaks.

I know we live in a digital world but there are still use cases for printing. An the erros above also apply on printing PDF

Is a rollback to 5.8.2 possible without losing configuration for the users? And if yes, how do i perform it?

Issue appears on different browsers (edge, chrome, firefox) and different systems (PC, Android) also with all extensions disabled.

You can still do with the browser file => Print .

interessting because CTRL+P is without a response .. but the outcome is not usable because of the iframes.
