    Hi there,
    I use DAVdroid for a couple of years already. I have HTC One M8-Verizon with Android 5.0.1, HTC Sense 6.0. I use it with my free Yahoo Mail (US) calendar account.
    Yahoo CALDAV sync stopped working a couple of weeks ago. I’ve uninstalled-reinstalled the DAVdroid via Google Play - no go. An error says “Server error while downloading remote entries”. I’ve collected ‘DAVdroid Exception Details’, will post upon request.
    Any ideas or fix ETA?
    Thank you,
    -Mike.

    Hello,

    Thanks for the report. It seems like DAVdroid sends two <calendar-multiget> elements by mistake. I can send you a modified .apk to test the fix, if you want.
