Cannot add/remove players from blocked-list

Since yesterday I can no longer add nor remove players from my blocked-list.

If I click "Unblock" on a players profile page (or on the blocked-list overview), the button turns grey, but nothing else happens. If I reload the page everything is as it was before i clicked the button, ie the player I tried to unblock is still blocked.

If I click "Block" on a players profile page, the button turns grey, but nothing else happens. If I reload the page everything is as it was before i clicked the button, ie the player I tried to block is still not blocked.

I've tried this from my iPhone and from my MacBook, from Safari and from Firefox, with the same results.

Anyone else has this problem?

Blocking doesn't work for me in the IOS app either. I can move the switch in a players profile to blocked: active, but when I revisit the page it's back to blocked: inactive.

I was unable to make such an observation. I play with smartphone, app and webversion.

How many players do you have on your blocked list?

Currently 66.

First time the issue appeared I had a lot more. However I have since then, on two occasions a few days apart, been able to unblock about 150 players...but after doing so, both times block/unblock stopped working again.
