Thank you for waiting!
The logbook issue should now be resolved for all future data.
I am extremely sorry to report that any previous data that is lost is unrecoverable, however from this point forward all new data and notes should be working perfectly.
If you have any issues at all from this point forward, please can you let me know via the app.
