The CalDAV interface seems to be out of order
Hello,
For several months, I use "aCalDAV" on my Android smartphone, and it worked very well. But since 2 or 3 days, I get an error "invalid server answer, check URL". But I have not changed settings (the URL is always
https://calendar.zoho.com/caldav/ ). Same phenomenon on my daughter's phone.
Are there a problem with this API?
Thank you in advance. Sincerely,
E. D.
