According to a Wednesday report by the organizers, the festival, scheduled for May 11 to 22, will certainly take place in 2021 but could be postponed to a time between the end of June and the end of July.
The festival was cancelled last year while rival European events in Berlin and Venice went ahead under strict health restrictions.
