I have no problem loading charts up via the APP or the MSFS Toolbar Beta system and it always remembers my log in.
However the Just Flight BAE146 EFB chart section frequently asks me to log in, and often than after applying the code supplied it tells me that this has expired. I have just tried four times to log on and the Navigraph system has a message saying that the BAE146 is linked with the account, but the EFB has shown a message that the ‘TOKEN HAS EXIRED’.
This is very frustrating.
An additional minor difficulty, that may be a Just Flight problem, is that the font used to show the code is not suitable and the text size too small, It is almost impossible to differentiate between S and 5 and B and 8 for example.
