Problems with notifications

Hi,

I have several problems with the notifications:

1) Couple of days ago all the notifications disappeared. Again. I.e. its
not the first time, it keeps happening time to time, in couple of
months or so. Very frustrating.

2) Only 50 newest notifications are displayed. So should you have more
unread notifications, its not possible to read them chronologically,
starting from the oldest. Nevertheless, the older ones seem to be
downloaded, as when you read some of the newer ones
and delete them, the older ones appear also when the device is offline.

3) For the past couple of days it is not possible to read the notifications offline.

Are these some kind of technical issues or just your choices? For me the described considerably devalues the user experience.
