Hi @frogerme,
I have a similar issue – the activity logs show that logging into the main site (goingruralhealth.com.au) successfully logs the user into the remote site (mulanagurranyin.goingruralhealth.com.au).
When I visit the remote site, I am not logged in.
I’m not as technical as @mubashiriqbal, but I tried to follow your instructions re: checking Network Inspector.
When I log into the main site, I can see the following entry when searching for wprus
in the Network Inspector for the main site.

There is no entry in the Network Inspector on the remote site. I’ve checked with my host Flywheel, and they cannot see any issue on their end.
There’s no issue in the console. I’m not testing on incognito mode (Chrome on MacOS 11.2.3, also tested on Safari). My permalinks are set right. Using the URL from the site settings. Kinda stumped here.
I should note that user creation/update etc all work. Just login/logout not working.
Would love your help!
