Hi @Aja Warnock Based on our research, there are a few possible solutions that you can try:
- In Planner, select the task that you want to copy. Open the task's More menu by selecting the 3 dots (. . .) in the task's upper-right corner, and then select Copy task.
- Or you can open the task's More menu directly from the board, and then select Copy task.
- Check and update if the Teams is the latest version.
- Uninstall Teams from your device, then reinstall it.
- Clear the Teams cache from your device.
- If you’re using the Teams desktop or mobile app, try using the web version: https://teams.microsoft.com/.
