I got org updated, following Ihor's instructions: Org mode version 
9.7-pre (release_N/A-N/A-afc529 @ ./org-9.7pre0.20240130.161905/)

If I were able to fulfill a good process to export from agenda to 
icalendar, maybe we could share an easy process, useful for a lot of 
users that miss a good android calendar visualization. Do you think it 
could be possible to export, in an async way, a calendar file every time 
when a new timestamp, Schedule or Deadline are added to a buffer? What 
would happen if an export process is already running and a new timestamp 
is added? Would it be robust enough or prone to errors? I can see that 
even if a footnote is not correct, the process seems to be interrupted.

Actual state: when I try to export to icalendar, the behavior is quite 
confusing:

+ [c] Combine all agenda files: I don't get any ics file. I don't know 
what is the problem.

+ [a] All agenda files: I get just an ics file. I thought I would get 
one file for each agenda file.

Best!
