In the Iphone App it is not possible to edit a subtask and change the name after it is saved.
Please correct this basic feature.
Thank you for bringing this to our attention.
I will forward this to our ios developer for further checking. We will notify you once we have an update.
We have made few update with the app recently and most of the issues were resolved. We will be closing this ticket temporarily.
Please feel free to reach out if you are still having this issue. We'll be more than happy to assist you!
Have a great day!
