This is a private comment.
I've happily using it and paying for it for years, but the list of bugs and niggles is growing, and there is no response to anyone's questions or bug reports. There is clearly no development happening, or even monitoring of the forums.
It's such a shame because it's been good to use, but if it's just sliding into disrepair and there are no new ideas for making it better, then maybe it's time to leave.
The same question
I agree. Today I paid for the next pro upgrade and received nothing. I will file a complaint with play store and look elsewhere. No task boards, no new features,... poor performance
