I was very disappointed too after purchasing pro to find out that shared tasks can not be seen on iOS devices. Good thing I bought it via PayPay and I have just opened a dispute case asking for a full refund. Projects I work with has 20 mobile users and not being able to share it with them make this app useless for me. What is toodledo thinking?!!!
I really think they have should've CLEARLY listed this limitation in their FAQ pages given how many of us found out that hard way.
I will be more than happy to reconside this app once this feature is introduced.
