Cannot turn on APU after landing

[trisager]

After the recent update, I cannot turn on the APU after landing - it won't power up. No issues before updating.

MSFS 2020.

There's been no intentional changes on our side with regards to the APU logic in the recent F28 Professional updates.

It'll be worth double checking that you have the GEN 3 and APU AIR switches both set to OFF before starting the APU (the latter will prevent the APU starter from triggering if left in the ON position). Note that the APU MAIN switch should also be left in the ON position for 10 seconds before pressing the START button, as that allows the APU intake door to open.

Hope that helps.
