Why Germany did not recognize the Enigma compromise

Did Germany suspect that its Enigma signals were badly compromised?

It knew something unusual was happening but never accepted that Enigma itself had been broken, explaining Allied accuracy through direction finding and other causes.

German operators understood that radio transmissions could reveal a previous location and therefore tried to move after sending. When Allied fire arrived quickly, they could explain it as fast direction finding, coincidence, or interception rather than proof that message contents were readable. Those plausible alternative explanations helped conceal the scale of the intelligence compromise. The habit persisted into 1960s NATO exercises, when Allied observers complained that German units still transmitted at full strength and revealed their positions even if message contents remained secure. The continuity shows why cryptographic security and emissions discipline are separate problems.
