After updating to 2.8.0 its not possible to change Stock Status anymore

Hello, the same thing happens to me. I am using wordpress version 5.8.1 and Stock Manager for WooCommerce version 2.8.0.
As much as I put a value in the stock part (0 or a higher value), when saving and returning to the page, it is as if no changes had been made.

I am having the same issue. Was working and then I updated and went to show someone how to use it, and nothing is updating, even when save pops up.

Made me look like a right idiot and was embarrassing, as I tested previous version.

I have the same problem but when I upload my stock file I get the message that the first ID is updated and then and error message “Une erreur critique est survenue sur ce site. Veuillez consulter la boite de réception de l’e-mail d’administration de votre site pour plus d’informations.”
Quelqu’un auraitune solution?
