I have an active subscription to the main SLP plugin as well as Power, Premier, and Experience. I am able to upgrade the main SLP plugin to 4.8 with no issue through the WordPress dashboard. However, I am unable to upgrade any of the add-on plugins (you can see in 2.PNG that I’m not given the option to upgrade them).
I would normally upgrade them manually, however when I log into my account (you can see it’s active status in 3.PNG) I am not able to download any of the plugin files (I get the message that’s in 4.PNG).
