This is an accepted solution.
Aibek is here from Speedimize.io
The pop-up should have the delay setting when you go to the Online Store -> Customize. If you use the standard theme popup, of course. If the app, then there should be such a setting inside the app.
At the moment, the default value is 5 seconds. There is another way. But then you will need to know liquid and configure scheme. But first, try to do as we said. If this does not work, it would be great if you find popup. liquid(in your theme, it can be called differently) and send the content here and we will try to help you.
Hope our solution will be useful.
