No preview thumbnails in talk


I’ve got the problem, that NC-Talk doesn’t creates or shows preview thumbnails of documents shared in Talk. The issue only exist in the browser (equal which browser)
In the Talk App on IOS everything works fine.

So here is how it looks (correctly) in the app:

And how it looks in the browser:

I think preview generator works but there’s an issue with displaying them.
But it’s really bad if you can’t even see that someone sent you something…
(like shown in the second Screenshot)

I am using:
NC-Version: 20.0.7
Talk Version: 10.0.5
With latest Nextcloudpi

Hope somebody could help…
Greetings Dominik
