Is T4-T4S connection on separate ticket, non EU passport doable on 1 hr 55 min connection? Should I take the chance or forget about it and fork out more than double my original ticket price for the connecting flight?

I have a MAD-DOH-TYO award ticket on QR departing from T4S, and a separate ticket on IB3723 AMS-MAD 12:10-14:50 to connect. OWE. The MAD-DOH flight was originally 17:40, then moved to 17:10 and then moved forward again to 16:45, making what was originally OK connection very tight, albeit still slightly above the MCT of 90 min.

Am very angry with QR cust rep non caring attitude who says ‘we never promised you a particular time of departure when you book a ticket from us’.

By now, given the date May 5th falls on public holiday or something, tickets are very expensive and to change the IB ticket I would have to fork out more than twice the original ticket price, not to mention having to fly at 7:35 am instead, meaning that I will miss visiting Keukenhoff which was my whole reason for transiting in AMS.

Any advice/ similar experience will be appreciated.
