I'm in the process on onboarding a team member to Wrike and they have a lot of recurring tasks. We tried to nest tasks into themes (tasks + sub tasks) but as I discovered only tasks can be recurring.
This has caused the person to not convert to Wrike.
I did read that recurring tasks is not a priority, but I hope the Wrike team reconsiders as it can have a huge impact for teams that nest related tasks to an overall task theme.
