The post-deployment Keps are beginning to age. Reports are that the satellite is running noticeably ahead, and automatic Doppler tuning is not very effective. Space Track has now released 5 objects which can be found in CelesTrak at:

They are currently the last ones, 2019-071C through 2019-071G.

They are currently tightly grouped, but running 1-2 minutes ahead of pre-deployment Keps. I would suggest trying the middle one, 2019-071E for now. Reports on agreement of individual objects welcome!

Thanks Alan,
Just had a pass and although better "E" still required a lot of tuning to stay decodable, will try a different one next pass.
