How to delete, omit or hide Back button

[karaga]

 I really need to hide this button. How can I do it?

It is not possible to hide the back button. What is the reason you want to hid the button, and maybe I can suggest a workaround?

Hello! Thank you for your feedback! We're building a program that has a "Start a shift" button. Then, it opens a view where the user can input some information. The previous view (where the only button, "Start a Shift", is located) hides. After the shift, the user goes to an additional view (that can be seen only if you start the shift) and ends the shift. After that, the user has an opportunity to start the shift again.

I have the following problem: after the user starts the shift, he/she has an option to go back and start the shift over and over again. I would be extremely grateful for your help 🫡

If you are having users log in to the app, then you should be able to hide the "start a shift" button whenever they are on a shift. Then when they finish the shift, the button will be available again.

This would be adding a 'show_if' to the view or a 'Only if this condition is true' to the action.

I would first create a slice on your table that shows all 'Active Shifts'. Something like AND(ISNOTBLANK([Start Time],[ISBLANK([End Time]))

Then for your 'show_if'/'Only if this condition is true', an expression like NOT(IN(USEREMAIL(),Active Shifts[email]))

If you are creating an AppSheet app for  time tracking , please be aware of the following points.

The post below discusses various aspects of time tracking through AppSheet in detail.

Essentially,  an AppSheet app's default time capture is user device dependent. So it coukd be different for different users, even if they have recorded the timestamp in their app at the same instant.

The automation bots could be used to capture server time but it will need app to be online and will involve any associated delays when the server time is captured after invoking the bot throgh say an action by the user.
