Hi, @newstore321 !
Katy here from Shopify. I hope you are well, and enjoying creating your store!
Usually when ads do appear on your store, these are generated by apps in some way. If you could share a screenshot of the ad you are seeing this would be very helpful. Could you also take a look at the apps that you have installed, to see if there are any apps there that specialize in pop-us of advertising?
To remove these ads you will need to uninstall the relevant app. Sometimes even when removing an app from your store, some residual code may be left behind, in which case you will usually need to touch base with the app developer directly to help you with this.
If you could however share an example of an add you are seeing, we can then help to pin-point this for you.
Thanks so much for your reply, @newstore321 !
I know you mention that it is sporadic, but would you be able to send a screenshot of the type of ad you are seeing, as an example? This will help in identifying the source.
