For the link here I am getting this error while testing on iOS
Below is the screenshot when I click on satellite this is what I get. What could be the solution?
Steps I did -
- Cleared cache of browser (Chrome latest software)
- Cleared cache of iPhone
- Restarted the devices
- Still not working. Can someone suggest please?

The problem is from the `Map` component in the page. You need an API key to make it function.

API key is already added.

I meant the key for **Google Map**. See this
**[Edit]**
The above is not the only problem with your app but is the source of the crash.
You have other issues such as you are using two different type of variable assignment that do not relate to each other.
This
does not equal to this
The third issue is that the `Latitude and Longitude` of the `Map` component expects a number not a text.

It was working on Android. Default Google map is used without keys. Not working on iOS. Main location is being fetched from this API shown in the image.

It shouldn’t work in Android as well as iOS.
