Are you sure you uploaded the LAST version on the client portal?
Because I installed the new version, and
1. it DOESN’T WORK
2. The server says the files were modified for the last time on 11 December (amazon plugin) and 27 September (wpfm pro).
Can you either explain or upload the updated plugins?
It takes a lot of time to run these tests, and it’s frustrating to be stuck testing the same old version of the plugin
