WC 3 Issue: Can’t Accept More Than The Default Amount

Since WooCommerce updated to 3.0, the Donations plugin has stopped working. The recent 1.0.9 update resolved the ability to save a product as a donation type issue, but now the plugin has another problem.

Donners can not give more than the default amount set for a donation. So for example, I created a donation product and set the default amount to $20. When users on the front-end of the site try and change the donation amount from the default amount to say, $40, and then add it to their cart, the cart total only reflects the default amount of $20, and not the adjusted $40 amount the user entered.

It’s been such a great plugin. Thank you for all the work you have put into it. Is there a way to resolve this new issue? Thanks for the help!
