I created a list about a week ago (Custom List) and created a view from the DataSheet View template - and it works just fine. Today I created another list (Custom List) and then tried to create a DataSheet View and it let's me create it but it does not actually display in DataSheet View. Its some other format.
I'm perplexed because of the fact that it works on 1 list and not the other. The lists are on different Sites, although same Site Collection. But it seems it must be a Site issue and not something like Browser, 32 vs 64, etc. - I open the two lists side by side (in Chrome, or IE, or whatever), and the one displays properly and the other does not.
