My app’s URL: [https://app.smallbrands.com.au/](https://app.smallbrands.com.au/) Hi, I have suddenly lost my ability to control visibility of a component based on logged in/logged out username. It was fine a couple of hours ago. Anyone else? ---

Do you mean that the feature doesn’t work? Or you can’t find it? Can you make a demonstration and share it? ---

It’s not appearing on the drop-down under Features. Sorry, how do I make a demonstration? ---

Show us with a video or screenshots. The feature is now under Filter. Maybe it moved since you looked last? ![image](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/2X/5/52d00373fd3f7443e158e29d7483a2ebe4d1e050.png) ---

It’s the same for both filter and visibility, across all components. Was fine this morning. ---

Doesn’t look like your username column is registering as an email column. Does your username column contain email addresses? ---

OK, fixed it. I had an entry in the email column that wasn’t a correct email address. Thank you for the clue! ---

Is it a problem to use email addresses as usernames generally? ---

I suppose that’s up for debate. I personally prefer to use my email as a username because I never forget my email address. If you want to use any per user or signed in user functionality in Glide, you need an email address.
