Hello Yame. Thank you for your enswer.
1. Breadcrumb step by step:
1.1. In google search console I am getting errors that there are 9 pages on my site with missing Item field - see attachment "MissingItemField_1" and "MissingItemField_2". This are all the pages which are not related with woocommerce store.
1.2. After google searching I found it as common problem. It seems that also the page link in Breadcrumb has to have "href" not only home link - see attachment "MissingItemField_3" and "MissingItemField_4". Looks like google don't like this
1.3. https://wptavern.com/google-search-console-adds-breadcrumbs-report-sends-out-warnings-for-structured-data-errors
The breadcrumps in my Yoast SEO are disabled - See "MissingItemField_5"
2. Translation
2.1. You have to be logout - on the page
2.2. Put something into chart
2.3. Go to checkout page
2.4. Click on "Kliknite tukaj za prijavo" - See attachmnets "translation_1" and "translation_2"
3. In search console I also get an error that there are pages with noindex. But investigating with google it seems that this pages in woocommerce are common marked with no index? Do you have any info about this. See attachment "NoIndex"
Thank you. I hope it is more clear now...
