Mollie link store to Prestashop account

[Gerrit Snel]

I am using the Mollie Addon for payments. I created a copy of the webshop for testing purposes.

In the Mollie settings of the copy, a message appeared stating that the shop was linked to another shop and that to prevent issues, it would be better to unlink the store.

I did this, but now the real environment is also no longer linked. When I click on the "Manage linked stores" button, I get the message: "No stores are linked to this account. To see the associated stores, please log in with the correct user account of the association."

Data sharing is also disabled: "An error has occurred while initializing the data sharing component. Please try again later. You can contact the module author if the problem persists."

Does anyone have any idea what to do? I can't find anything that points me in the right direction to solve this problem.

In the copy environment, I created another account, linked the store, unlinked it, linked it again, and deleted the account to see if I could relink it, but now I have the same problems in the copy. I can't provide another account to link Mollie/the shop to another account.

Thanks in advance!
