Free version app data cannot send to server even after purchased the paid app

[kungheifatchoi]

After migrating the data from old iPhone to new iPhone, the free GasCubby app didn't appear in the new phone. So I followed the instruction to buy the paid app in the old phone, then go back to the free app, tried to send all data to your sever, but it kept saying, ad-free version is not installed.
What can I do? I don't want to key in everything again... Pls advise, thanks.

Version:
Gas Cubby FREE 2.7
Paid app version 3.0.13 build 3.0.13.4

At this time, please continue to use the free version of Gas Cubby 2.7. We will soon be releasing the free version of Gas Cubby 3.0 and this will allow migration from the free version of 2.7 to the free or paid version of 3.0.

We apologize for the inconvenience.

I can't use 2 phones at the same time any more. I have to pass the old phone to someone else asap.
When will the free version 3.0 released? Or can u suggest any feasible solution to keep my old data? Please...

In the next few days, you will see an update released for GC 2.7 free that allows you to save your data to the back up server via the Setting menu.

Save the data, a link to the back up file will be saved to you. Follow the instructions shown in the lost data thread above.
