How to mark articles before yesterday as read in the filter，I tried date:P1D/, date:/P1D, date:/P-1D，but it didn’t work. Here are the rules:
https://freshrss.github.io/FreshRSS/en/users/10_filter.html#with-the-search-field
By date of discovery, using the ISO 8601 time interval format:
date:<date-interval>
Before a given date:
date:/2014-03
Can anyone help me? Thank you!
