@javiercn, can you please look into this. We should fix this as part of 2.2 release.

@mkArtakMSFT This is by design. What Doug is referring to is the cookie policy, which governs non-essential cookies, like the temp data one. This was discussed at the time and we agreed that it is not guaranteed for the site to work if the cookie policy is not accepted.

This can be opted out by making the temp data cookie essential.

services.AddMvc()
   .AddCookieTempDataProvider(o => o.Cookie.IsEssential = true);
