Shopify Theme Update

Is it necessary to update themes? I’m using shopify’s Origin theme and an update is available. I don’t know how to update. I’m currently running Facebook ads. Will there be any problem if I update? I’m also using Meta pixel code in my store. Should I need to set up meta pixel again in my updated theme or it’ll be automatically copy there? Please anyone tell me the proper way to update theme. Thanks.

If you are satisfied with your current theme, there’s no need to update it. However, if you are using a Shopify version 1 theme, it might be worth considering an upgrade, as it could enhance your store’s performance.
