I couldn't play against a friend online on grid legends last night

Please sort grid legends out we couldn't play online last night I never blocked her but it saying unblock when I kept looking up her details when she was online I mean her details about if she was on or offline but when I kept unblocking and trying to invite her into my game nothing happened and the same when she tried to invite to a party on it aswell was there issues with the grid legends server or something because we couldn't do anything and we didn't have any issues on Wednesday we blocked other people coming in but never her so was there something wrong with the grid legends servers last night because we're hoping we can play tonight sometime otherwise what's happening please let me know urgently thanks
