I use IB as my Hilton airline partner for earning Avios as they give 50% more than BA. Then every quarter or so I transfer them from IB to BA.
When popping over to the IB web site do that today I saw this message:

And sure enough, after not reading things correctly and mistakenly transferring Avios from BA to IB

I can't get them back again on either the IB or BA sites

.
Anyone know what has happened to the IB to BA route? I can't see anything about it being removed in other threads.
