Hello,
Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.
I can check that the SEO title is being applied correctly to your page:

You will have to wait for Google to crawl your site and index the changes and it can take some time. The changes are not reflected in the search results as soon as you make them. Can you please confirm when you have made the changes to your page’s title?
Looking forward to helping you.
Hi Jaideep,
The changes are made at least two weeks ago. It seems the description has changes, but not the order in the title and separator.
Hello,
Please note that recently Google introduced changes to how it generates the titles to display on SERPs and it’s automatically changing those as per the algorithm.
