I booked a train via SBB for April 19th from Interlaken East Station to Florence.
The details of the reservation are shown below:

After booking, I recently checked again and noticed the route has changed. It seems the change was made due to construction.
I haven’t received any notification via email or in my booking history, so I’m not sure if the change is correct… I’m quite confused.
Even when I go to the ticket page, it still shows the route from before the change.
The screenshot shows the route I found by searching on SBB for the same departure time.

There is also an 8-minute transfer time.
Will there be any issues traveling on the changed route?
Since the ticket page I booked shows the route from before the change, is there no need to rebook or modify it?
I’ve heard that delays occur quite often, and given the 8-minute transfer… if the train gets delayed during the transfer, would the station allow me to switch to a different train if I inquire?
