Samsung internet browser ignoring set-cookie on Ajax request

Question

After logging in I am setting some cookies, which works in FF, Chrome, Edge etc. However for some reason, Samsung Internet Browser seems to be ignoring my cookies.

I've got cookies enabled, and it is accepting cookies from other sites, but I can't figure out why it won't accept them. I've got this capture from my server:

HTTP/1.1 200 OK
Content-Type: application/json
Set-Cookie: token=e1c137y8WEZItXVWExXBWRyQl9mxgxEvEMG++F6pzwart%2FAO0lTSA3tL48oeHclD%2FLQMdXWhgXvefpGR3QGMqwMe8cg%3D; HttpOnly; SameSite=Strict; Path=/; Expires=Wed, 08 May 2019 07:03:43 GMT
Set-Cookie: email=%2FwGLVu+6Yv5fYpSyZwRE8TIi0MlZZ6WaN+OaKusCF6pEyQjomquJmWwqSgrcHg2dcBeMBU%2Foeg%3D%3D; HttpOnly; SameSite=Strict; Path=/; Expires=Wed, 08 May 2019 07:03:43 GMT
Set-Cookie: testing=TESTETSETESET; HttpOnly
Server: Rocket
Content-Length: 56
Date: Wed, 01 May 2019 07:03:43 GMT

{ ... }

I've tried changing the HttpOnly, SameSite, Secure and domain settings, but so far nothing.

Any ideas?

Samsung internet version 9.2.00.70

Edit:

It seems like maybe it's because the cookies are being set from an Ajax query. I changed it to be a response from a normal form POST, and it seems to have worked. More digging...

Answer 1

Turns out it was due to my Ajax request. Once I added credentials: "same-origin" to the request, it works as expected.
