If the notification does say that your reservation is cancelled then it is cancelled. 

If the notification does say something different and this is just your interpretation it's most likely not cancelled (see the general rules).

You should include this message here even if it's in german. Otherwise it's impossible to know what is written in your concrete message.

Normally this does mean that you did book a ticket. 

Are you a railpass holder and did book just a reservation or did you buy a ticket with DB, too? Makes a difference. 

General rules:

If the train number did change, the old reservation isn't valid any more. For german trains, you do often get a new reservation then one hour before departure.

If the train number didn't change, the reservation is still valid.

You do get a notification with every change of the timetable even if it's just a one minute difference.

That’s the weird thing. The app (on My Journeys section) says ‘Trip Cancelled’...

and clicking in to the journey shows the below.

On Original Itinerary it has the German message that I can’t click on to read the rest of…

Yes, passholder with reservation.

Train numbers are exactly the same.

DB is well known for sending scary email for any time table change. I had 4 of those in connection with my Interrail trip last month. All 4 said that my trip was cancelled. My reservation was Utrecht-Basel-Hamburg-Copenhagen-Gothenburg.

At the end all my reservations were valid and the change was that the train in Hamburg arrived 2 hours later and the train to Copenhagen arrived 45 minutes later.

As long as the train number is the same, your reservation will be valid. I double checked that at Reisezentrum in Hamburg.

Just if you are interested:

The information you can't click on has been just this: information. It did say: "Aufgrund einer Migration im Vertriebssystem der SJ (Schweden) können vom 16.-27. April 2024 keine Reservierungen für SJ-Züge (X2) für Reisen ab dem 4. Juni 2024 gebucht werden. Buchungen von und nach Schweden für Reisen ab dem 4. Juni 2024 sind wieder ab dem 27.04.2024 möglich." 

It did just inform travellers that DB could not book connecting trains to Sweden.
