I came back to a Page days later and all my Dataset Icons are lost. But when i go to Repeaters or Items i can link them to the Dataset but i cant change settings on that Dataset.
I spoke to one of my colleagues and she has suggested a workaround. Try zooming the browser out so that you can find all datasets in the page - they are like squared icons that hover on the page.
In any case, this shouldn’t be happening, so feel free to contact our support team here so they can look into it for you.
