Yes can confirm a lot of logos are blank or have changed. It would be nice to have logos without transparency too. For example BBC News or the BBC 2 SD logos are harder to see with transparent letters in them.
In Ireland Oireachtas TV has lost its logo too.
Yesterday channel and Now 70s has no logo.
HGTV UK still has the old “Home” logo.
Court TV UK has no logo since it launched last year.
Sporty Stuff is a new channel too with no guide data or logo.
