There many exchanges where CLAM wallets not works for long time (few weeks)! It is Polonex, Cryptopia, YoBit.
As well, CLAM delisted from integrated in coinomi exchange and You Can't exchange on ShapeShift CLAM anymore! No any comments from support.
Not any explanation I can found anywhere!
All of this is really scary signs!!
I am Experienced crypto  investor and trader and can tell you, that CLAM developers, have to do something ASAP!
Because it is close to critical time average investor patience . SOON people will lost they trust and start too DUMP CLAM! Only this year Same signs was
with: VPN coin, Shadow cach ,Club,IXCoin,Pkb, so I dump them after few weeks of unstable works, just to save my money. I have to dump BEFORE price  is dramatically down!
I really like CLAM and hold it since it start, but I can't afford to lose money!
So, I hope the  CLAM team will do something about situation and post here some updates about progress with exchanges.
