HI Joe
Well thought I would test today on a longer sector without a fuelling stop so flew KBFI-MPTO.
Showed me online all day, 7.6 hours and no issues with crashing or anything.
Stopped and PIREP and got my flight points but I didn't get the box indicating that my flight had been saved.
The option to upload flights is blanked out.
Database to Dropbox.
I didn't ANYTHING different to the three flights I filed ok yesterday, except not resetting the database.
