UPDATE: the problem seems to occur ONLY when you enable “Hebrew Date for every day” option, which was my default for many years. Disabling it bring the calendar back to life in 2020. However before 2020 all worked fine and it would be nice to bring this option back. Thank you

There are no events generated for iOS since the end of 2019! I tried removing the calendar subscription and re-adding it multiple times. Ideas?
