in both web and desktop versions, In the agenda view it is not possible for me to collapse items, neither individually nor recursively. Only “collapse all” works (attached screenshot)
[2021/11/21] I just checked and realised that this error does not occur with new nested items, but only with nested items created before the date I posted this message.
[2021/11/22] And the nested items created yesterday that worked yesterday no longer work today.
