Do widgets work on a tablet or on the website?
They are a phone feature: iPhone (iOS 16 and later, Lock Screen widgets on iOS 16+) and Android 8 and later. The website has no home screen; the same numbers are on each dashboard.
From the guide Home Screen Widgets (iOS & Android).
Widgets meant for other account types
Some widgets only make sense for one kind of account: Occupancy and Applications are for landlords and property managers, My Lease is for tenants, Time Clock and Invoices are for contractors. On Android those are kept out of your home screen's widget list altogether, so everything you can see there will actually do something. On iPhone that list is fixed by iOS and cannot be filtered, so a widget that is not yours says who it IS for on the preview card, before you place anything.
Either way they stay listed in the in-app gallery under "Not for this account", with a picture and a line naming who they are for. A widget you cannot see at all is indistinguishable from one Seayora does not have, which is the more misleading of the two.
