Problem with multisite

Hello,
I’m writing about a problem I noticed using this plugin with a multisite configuration.
I have a website which is a network, each site is representing a couple of these entitites: country and market (example: /it/it) .
If I change the value of the MailUp console host field present inside the “general settings” tab, referred to the site number 1 (I’m inside the editing page of the plugin for this site), the plugin saves the data (the row of the option named=”wpmailup”) into the original table “options” (referred to the original site before the creation of the network); it doesn’t save the changes into the table “options_N” (where N is a number that represents the single site inside the network)

As you imagine, the problem rises on the front office: the page requested by the user, loads the data from the corresponding table (options_N), so it finds a wrong value, because the correct one is stored only inside the original table of WordPress (not used by the network, anymore).

Is it planned on your side, to correct this bug in the next versions of the plugin?
Our desire is to have the behaviuor coherent, so to have the data saved in the table used from the front office.

Kind regards
