Hi,
since the last App update for iOS (I have iOS 10.3.3) I unfortunately can not access the logbook anymore. Other areas of the app are working, but the logbook just keeps loading.
Furthermore, the dates of the sensors of the PL4 are wrong in the sensor charts. When accessing the charts of any sensor it says "No data available for this period. Please try with a larger period by clicking at a zoom option above."
When doing that by clicking for example "week" it jumps to July 2027 and shows old values, although the PL4 is synchronized to the current time.

Thanks for any help
