Tap your name in the corner and pick Ask Clayside support. Type what happened and send it.
It reaches a person. It is not a form that goes into a queue nobody reads.
What to say
What you were doing and what happened instead. "I pressed Save score on the Tuesday box and it said something about a tiebreak" is plenty.
You do not need to work out why. That is our job.
Getting an answer
If you have a confirmed email address, you get a copy of what you sent and the reply comes back to that address.
No address yet? Add one under You first, and replies can reach you.
Both your copy and ours carry the same number, so a reply and the original meet in a search of your inbox.
What we can see
Which screen you were on and which club you are in, so nobody has to ask. Not your password, because there is not one.
Your address is used to reply to you and for nothing else. It does not become a list.
