This happened to me too, see first post on this page.
I sent a tweet with the problem to Nordeus and they gave me two tokens as an apology. Doesn't make any difference to the result but 2 tokens is still 2 tokens.
Meanwhile, today while bidding on a player, going into the 5th round, I bid with about 5 seconds to go, against one other, but somehow got knocked out of the bidding, so lost 5 tokens and no player.
Something tells me this is not my connection but Nordeus playing games to get people to spend money.
App install issue apparently - I was advised to delete App and redownload. This I did, rebooting device after delete and before re-download. After a quick friendly, everything is now OK. Recommend you try same.
Any formation or tactics advice given is based purely on experience with my teams...
