First time poster but long time user. am having a bit of difficulty, and thought I’d best ask for input. This morning I went to establish an alert for any B722 type aircraft flying into KRIC, an alert I had previously enabled in the pas. Now whatever aircraft type I enter is shown as invalid, be it B738, A332, E190, etc.
I’ve never faced this issue in the past, and ha set p similar alerts for years now
