Yes,
a well known strange and not correct behaviour evey time you “touch” the ILS or Approach on the FMS or Garmin, already having a valid flight plan loaded and cleared, with an XPDR assingn and radar following.
No ATC IFR clearance should be requested indeed, instead it appears in ATC options. It’s wrong and we don’t know why Asobo does not remove this behaviour, maybe so difficult? Maybe not important to them?
And yes, correct, if you ask the clearance almost every time ATC the assigns a completely wrong altitude/FL as if in fact it was another FPL with different level or current aircraft position wouldn’t be known.
Asobo corrects ATC things with every SU, still not clear to me why not this feature…
