Email button not showing on phone

The email button is showing on my computer

but not showing on the two phones I have tested it on !

Any ideas

Do you have any visibility conditions on that component?

No …
I have deleted the component and re done it several times
I have now placed a button to compose email and although the button appears on the PC screen and on the phone, it functions on the PC screen but not on the phone…

Can you make the app copyable so we can see the settings behind the scenes?

I was using a column in the table with the email address in (email column).
When I type the email address in the custom box it works…

Do you have that email in every row? It seems like you are filtering that tab, is that correct?

no - But I am happy that I have got around the issue by just manually entering the email address
Sorry to have perhaps wasted your time…
