Favicon Display Issue in Shopify Store

TITLE: Shopify Favicon Fix — Quick Shopify Expert Needed

THE JOB
I need a Shopify expert to fix a favicon issue on my store at tavo.ie. The favicon has been uploaded correctly through the Shopify theme editor but is not displaying in the browser tab. I have already tried the standard fixes and nothing has worked. I need someone who knows Shopify's theme code in depth to diagnose and fix this properly.

WHAT I'VE ALREADY TRIED
- Uploading the favicon through the Shopify theme editor
- Checking the favicon tag is present in theme.liquid
- Clearing browser cache and testing in incognito
- Re-uploading the image in different formats

WHAT I NEED
- Diagnose why the favicon is not displaying on tavo.ie
- Fix the issue directly in the Shopify theme code
- Confirm it is displaying correctly across Chrome, Safari and Firefox
- Brief explanation of what the issue was so I understand it

REQUIREMENTS
- Proven Shopify theme development experience — please share examples
- Comfortable working directly in Liquid and theme.liquid
- Available to start immediately
- This is a small quick job — do not bid if you plan to overcharge for a 20 minute fix

BUDGET & TIMELINE
Fixed price job. Budget is €15–€30 depending on complexity. I need this done within 24 hours. Please do not bid above budget — this is a straightforward technical fix for someone who knows Shopify code well.

TO APPLY
Tell me briefly what you think the issue might be based on the symptoms described. Anyone who can give me a plausible diagnosis before being hired will go straight to the top of the list. Generic bids will be ignored.
