Custom product tabs not showing

Hey guys!

I have tried adding the additional product tab via ACF Pro (Advanced Custom Fields) and then showing it on product page. I followed several tutorials, but the tab never showed.

I wrote a support ticket on WooCommerce and they pointed me to you, can you please help me?

I also created a support ticket via ACF Pro, ticket ID: #1567009337.

What I tried?

– I tried to disable all plugins: tab still not appearing
– I tried to switch the theme: tab still not appearing
– I tried to clear cache, disable cache, test via Sizzy without cache at all: tab does not show
– I tried to add a custom product tab via custom tabs plugin: still not appearing
– I tried to add a custom product tab via ACF Pro: still not appearing
