When visiting some websites, the red Z icon for auto fill and login is missing.

e.g. 1 - Browser extension doesn't recognise GST India tax filing portal.

I saved the password with name gst.gov.in and URL https://services.gst.gov.in/.

e.g. 2 - Browser extension doesn't recognise GoDaddy login page.

I saved the password with name godaddy.com and URL https://mya.godaddy.com/.

I checked in the same session that the action icon is appearing on common websites like facebook.com - that's working fine.

GST and GoDaddy seem to be obvious sites to get right. LastPass auto-login button appears for me on every login page, including these.
