I spoke to the call centre yesterday while experiencing this problem between Drury Lane & High Holborn. Agentr undertook to raise it with ‘on street’ team; acknowledgement that it was a general issue. I’ve also raised it by email quoting specific examples from last week in Drury Lane area and Breams buildings/Holborn Circus/Hatton Garden. Still waiting for a reply.
Seems to follow on from recent wholsale replacement of the docking heads but no proven link.
Better today? ATM the website reports 1 free space at Breams which tallies with observation from my window.
