I have seen that when you don´t reach the target altitude in time for the given waypoint. ATC will not command the next altitude unless either you are in range for tower handover or you are already levered at the assigned altitude ATC instructed before. So if you have a wrong altimeter setting or you are following another approach data than the one available in game this may happen. In the best case ATC will instruct you to expedite descent but sometimes it just don´t do it if you are descending but not fast enough.
Indeed I found that sometimes the handover to tower happens extremely close to runway if the latest waypoint is also too close to runway, which does not allow to descent in time or to reduce speed. Or even that handover is not performed at all and you miss the approach.
To double check that the approach data used in game and the one in the charts are matching you can open the approach in Little Navmap and there you will find the altitudes for each waypoint and you can compare with the ones in your flight plan. The problem is that if ATC instructs you to follow a higher altitude than the one in the charts, if you reach the next waypoint at the correct altitude acconding to charts (which should be the safest way) then ATC does not trigger the supervision of the next waypoint and then it will most likely don´t trigger the handover to tower as well. This needs to be improved in game definitely and ATC should stop supervising the previous waypoint altitude once you reach the next one. On the other hand it should handover you to tower at a predefined safe distance, independently from the distance of last waypoint to runway.
What I do is to follow the charts when I see that any of those issues is likely to be reproduced (as soon as you detect altitude instructions inconsistencies), to resync altimeter even if ATC did not provide the new baro setting and to reduce speed to the min to give time to ATC to perform the handover to tower.
If I had no handover to tower then I decide if I want to go around or land like there´s no tomorrow if I´m too tired of the flight or the bugs
