Unfortunately, I just realized that since 05.10.2019 no update messages have been sent.
The problem was that I implemented some new features. Among other things also for the range of the daily notification. Here I have added a selection box to set the time at which the daily notification will be sent. The function is given so far, unfortunately I forgot to fill this field with a standard when registering. This has now been corrected and all notices have been sent.
Hopefully it did not cause any problems.
