If you encounter any challenges with third-party applications or a particular website, I recommend reaching out directly to the respective app developer or site publisher/host for further assistance. Here is how
Instagram is not an Apple Product. Contact the app developer here --> App Support or Instagram Help Center

Instagram, Facebook, and Google continuously update their platforms and user interfaces to optimize the experience across different devices. It's possible that a recent update to the platforms' user interface inadvertently caused your iPhone 11 to be classified as a Mac due to a design or compatibility oversight.
- Check the device name in your phone's settings to make sure it is not something that could be mistaken for a Mac.
- Update your iPhone's software to the latest version.
- Clear the cache and data for the apps that are misidentifying your iPhone.
- Report the issue to the app developers.
