I think that’s odd change off subscription. I already paid per year /12months. So changing to Kurviger 2 would require another new payment. Just for feature that isn’t implemented to the one I already have.
It doesn’t really make sense to me why Pro wouldn’t be upgraded as is.
Surely cause of some Technical issues. From user point I think it’s odd.
You may continue using Kurviger 1 Pro.
(it will be maintained for new Androids)
If you need new features you can upgrade to Kurviger 2.
The model Free/Pro is no longer sustainable, for further development, third party services,
maintenance, hosting, servers, etc. If we continue with it, Kurviger will stop to exist. Therefore subscriptions exist per platform.
