Hey @BadForm
Sometimes, theme developers makes changes in the update so that’s why they might have made this change, you can still make your logo clickable by adding some custom code in your header.liquid file. If you’re not familiar with coding, then I would highly suggest you to hire a Shopify developer who can help you out in making those changes. Feel free to let me know if you require any assistance and I would be more than happy to help you out.
If I managed to help you then, don’t forget to Like it and Mark it as Solution!
Best Regards,
