Redis Magento 1 v1.14.1.0 - Homepage Mini Cart not updated after added an item until refresh the page again

Hi,

One of our clients production website implement based on the Redis with CDN in Live server. The issue was Homepage Mini Cart not update after added an item until refresh the home page again. You could view the issue in this video,
https://www.useloom.com/share/f98ef7e12f194af79a3084daf957322c

Already tested, 1) Cleared both redis cache and DB (Magento cache and full_page_cache set to Redis cache) 2) Flushed CDN 3) Checked in browser Incognito Mode

We could not reproduce this issue on UAT (https://bunda-uat.ns-staging.com.au). In UAT, we did not configure Redis or CDN. I guess, this issue should be relates with Redis due to it does not occurs in UAT.

Could you please let me know the reasons for why this kind of issue might occurs? You could reproduce the issue in this URL, https://www.bundabergrum.com.au/. I look forward to hearing from you soon. Thank you.

Best regards, Dasitha.
