Hi onthego
Please, it would be easier if you can open different threats for each topic... 🙂 In any case I will try to answer you.
Regarding the multi-inventory issue, we will need to see the settings as I wasn't able to reproduce it in my staging site. So please, I have to ask you to open a private ticket and provide us there with your website credentials in order to take a look. Also, it will be useful if you can tell us a product that is experimenting this issue. This is the link to open the private ticket: https://stockmanagementlabs.ticksy.com/ticket/
Regarding the users limitations, please, accept my apologies cause I had a lapsus and confused 'Action Logs' (the add-on) with 'Inventory Logs' (the feature). With user role editor you can make that the others users can't see the ATUM settings, but then they want be able to see the logs... In any case, you can always achieve this with custom development, but as we don't offer this service you will need to hire a developer.
Best Regards,
Andrea.
