Does anyone know, why my Task List View opens in Quick Edit by default? and how to fix it?
It seems you have created a view with datasheet which tends to open in the edit mode. You can set it to default Standard view. Refer this link to change the default view of the list
All the best!
Someone probably created a custom View and set it as the default. Browse through the existing Views and find the original View. Edit that View and make it the default.
I just ran into this. I looked at the view in SharePoint designer, the view Type property was set to "GRID."
Comparing it to a normal view, I changed the type property to "HTML" and it loaded how I wanted afterwards.
