The issue with ad-blockers
Certain ad-blockers can accidentally block features of the Shopventory app itself. This can lead to things like unresponsive toggles or the inability to get a message if we need to reach out about something as crucial as billing.
A simple fix
Most ad-blockers allow you to "whitelist" or permit certain sites. This means the ad-blocker would create an exception for Shopventory.
You'll see that in the settings of your browser extension/add-on.
You can also disable the ad-blocker manually on the Shopventory page.
