We have Magento 2.4.3 upgrade after any
action/event perform we can't appear with
success/error messages. if we have to go to other pages then the message will be appearing there.
I too faced this issue in my projects. I was used Multi store view on a single website. So the message is not showing in multi-stores. I have used the below solution,
The issue was caused by cookie configuration for subdomains.
In Store > Configuration > Web > Default Cookie Settings :
- Set Cookie Path to /
- Set Cookie Domain to subdomain.domain.com
Then clear cache with
php bin/magento cache:flush and go on the front of the page where messages are not showing, clear cookies in the browser and refresh.
Please try the above solution
