Delete Button - Inconsistent Results

[DM2018]

I have a delete button at the top of a 'Details' screen. The delete function works perfectly for me in PowerApps studio and also in the published web player version. However, the same button does not work for end-users using the same published app. Stranger still, when I log into PowerApps and use my app on the end-users machine and Browser - the button does not work!

If it's not a permissions issue and it's not a browser issue (from what I can see) what could be causing this behaviour? Formula below:

Remove('BIM Performance','BIM Performance Gallery'.Selected); If (IsEmpty(Errors('BIM Performance','BIM Performance Gallery'.Selected)), Back())

Hello DM2018,

Can you try 
Remove('BIM Performance',LookUp('BIM Performance',ID='BIM Performance Gallery'.Selected.ID)) instead?

Hi, thanks for the lightening response but that's not working - not even in the studio preview. It's like the button is no longer clickable, so it doesn't seem to be a connection or data transfer issue

I would delete the button and create a new one with the same functionality..

Wow, it was that simple. I've deleted the button and re-created it. Both my formula and your formula now work for the end user.  I'll never know why it didn't work before, but it does now! So thanks for the quick and simple solution, I would have spent even more hours trying to get to the bottom of it.
