Hi Kisha,
If the offer has a restriction on browser type or device, it will be in the offer’s description.
If not, it can be something on your side.
It’s also possible that the geo-redirection feature is affecting your experience. If your location isn’t a location allowed by the offer, you need to access it using a proxy or VPN that can change your IP address. But, in this case, you should test the actual affiliate link and not the preview. If the preview has an issue, but the affiliate link is working, then it’s not a problem.
