Free games "problem adding to your account"?

Adding this game worked for me.

Happened to me a couple days ago, but it's fixed now.

Not only me: https://www.steamgifts.com/discussion/20mW7/there-was-a-problem-adding-this-product-to-your-account

I've been getting this error for the last few days. My solution was to open SteamDB and install from there, it has worked everytime so far.

I had the same problem yesterday. Still continues today.

I noticed it only happens on browser and not the client. (At least for me.)

Same for me when I try adding something via browser. But it works when I try adding them in the client.

Idiots at Valve thought it to be a good idea to make some changes to Steam code before a major sale. What could possibly go wrong?

Valve broke adding free packages (even the "Add to library" button on the store is affected), wait for them to fix it.
You also need to update the SteamDB extension to 3.6.7.
This is broken because store.steampowered.com and checkout.steampowered.com must have same sessionid cookie.

I get that when I try to add it via web browser, but on the Steam client there's no issues.

I'm using Chrome. Not sure if it happens on Firefox and others though, haven't tried them.

yeah broken, you could use links of the form steam://instal/2445680 instead

yeah broken :(

happened to me two days ago, then i went to steamdb.info, clicked on install and it worked.
but on both sites, steampowered and steamdb, the "add license" didnt work, only if i pressed "install"

Still happening to me

Short update: SteamDB add packages works again.

This problem still happens using a browser (at least, on Firefox), but it worked for me using ASF with this game:
https://store.steampowered.com/app/2078290/Queen_Beast/

Logging out of my Steam account in the browser and then logging back in seems to temporally fix the problem for me.

I had to delete all my stored cookies for the domain steampowered.com and log back in to get this to work on Firefox, just in case the logout/login method still isn't working for some.

I find that as soon as i enable the augmented steam extension it kills the working cookie

I can confirm that logging off and relogging makes it work well in browser - without touching anything related to extensions.
