Welcome to immigrationboards.com!
I didn't apply as Spouse of Irish National, but I have a bit of data on the application times based on posts in the other timeline threads.
It looks like everyone above thought this topic was for timelines for citizenship based on spouse of Irish citizen rather than applying for stamp4 on basis of being married to an Irish citizen.

Application based on being married to an Irish born national for 19yrs applied February 2018.
Return of passport and receipt of application fee February 2018.
I haven't received anything else since still waiting. I emailed them two or three times but just keep getting a generic responses, I'm hoping that I'm not being punished for Brexit.
