I just checked availability on a connection on https://www.interrail.eu/de/book-reservations
Because the critical connection was available, I bought the interrail pass. Now, if I use an incognito tab, the connection is still available, but with the pass, it shows up as “unavailable”.
This is, at best, scammy and bait & switch behavior.

You cannot use this module to check availability without buying a pass.
If you look up a train, then it shows directly below the "Book reservations” button:
Which trains you were looking into and when? In a lot of cases there’s an alternative, reservation free (exceptions exist, like Eurostar).
