Greetings.
To get my work done, I had to switch from master branch to stable, but now I started getting "invalid duration format" error when trying to create my daily agenda: org-duration-to-minutes: Invalid duration format: #("12:45-14:15 +1w" 0 15 (fontified nil org-category "schedule")) Here is the corresponding row, and the preceding row, from file schedule.org: <2021-04-15 Thu 09:15-10:45 +1w> <2021-04-19 Mon 12:45-14:15 +1w> Any hints?
