Asking your experience in reserving renfe tickets with Rail Ninja app

Hi! I would like to ask forum members of their experience (if any) in reserving Renfe tickets using the Rail Ninja app.
I’m representing a group of pilgrims from the Philippines who’ll be walking the Camino Ingles during Holy Week from Ferrol.
Reservation for the accomodations confirmed before buying our plane tickets last November.
6 weeks ago, I purchased our round trip Renfe tickets (Madrid-Santiago-Madrid) using the Rail Ninja app. I got a notice after purchase that the tickets were under process since it was an advance booking (March 22 is the 1st leg n April 1 is the 2nd leg of the trip).
My last update 1 wk ago sent thru email was “that the reservation was received n already processed but the seat assignment is a little bit delayed by the supplier. The actual train tickets will be issued only when the seat assignment becomes available and will be sent thru email.”
I’m a little bit worried that I might have been scammed.
Any thoughts or suggestions? Thanks

Thanks for the reassuring messages.

This is an update on my inquiry on the rail ninja booking platform.
Yesterday, I requested an update on our tickets since the departure date is 10 days away thru the platform’s support service. I got a reply that our chosen departure date has been changed so I requested a refund. Within an hour after the cancellation of the 1st leg (Madrid to SdC on March 22), I received another email regarding ticket change of the next leg, SdC to Madrid on April 1 (from cost saver to flexible) n the cost of the difference ($132) should be paid which I did. I was surprised later that not only the 1st leg but also the 2nd leg cancelled! And I was assured of a refund.
So, our grp of 4 decided to fly to Santiago n return to Madrid by train (booked thru Trainline).
