The link was established on the US site, but the editing rights of the title are on the UK site. Now a word in the US site title has been judged as trademark infringement, and the link has been removed. Then I used the template to delete the link on the UK site and waited for more than 48 hours, and then used the multi-store template to refresh successfully. The link also came back, but the title of the US site still did not sync successfully. Every time I go to the US site to open a case, the customer service tells me to go to the UK site to handle it, but the customer service of the UK site tells me to go to the US site to solve it. It has been 1 month, and I am very confused.
