I set my view settings, but they always randomly change - I think they are reverting to default. For example I NEVER have Assigned showing as it's just me and I don't use the feature. I ALWAYS have two task custom fields display on my main projects; Action Notes and Notes - I use these two fields all the time. But throughout the day suddenly I'll go to a project to do something in tasks and my custom fields have gone, and assigned is showing again - I spend all day removing assigned and adding but the two custom fields.
I've reported this bug before... and had conversations with support but I keep getting 'forgotten' about. It's quite frustrating having to keep making these changes throughout the day.
