download online-GMX-calendar to my smartphone

[weselpesel]

Hello,

__short question:
how can I download the calendar-data from my GMX-online-calendar to my smartphone??

__the background of my question:
for month DAVdroid synchronized my calendar-dates with GMX with no problems.
Yesterday DAVdroid gave me an error-message like "server is not available".
I tried to open the gmx-calendar manually in my laptop-firefox-browser. but i got an message like "ups, something went wrong"
OK - there seems to be an problem with the GMX server.

But now my smartphone-calendar is empty !!!!!
But the online GMX-calendar is all right.

I want to download the calendar-data to my smartphone. But what exactly does "synchronize" mean?
who is the boss? my smartphone or the online-gmx-calendar?

i am afraid to lose my calendar-data !!!!!!!!!!

thanks for any hint !!!!!!

liebe grüsse
jochen

SOLVED!!!

I learned how to back up the GMX-calendar in an ics-file.
and the i dared to click "kalender neu erkennen" ("re-recognize calender"?)
now everything is fine

it would be great, if the manual would be easier for non-technicians like me.
