Theme auto update still not working even after updating to 3.4.6

Hi,
I’d posted this before in another thread as I had been experiencing problems with all my sites on Enfold with autoupdate for some weeks. The problem disappeared for the last update but now it is back.

I am not able to use autoupdate for the theme from 3.4.6 to 3.4.7 I have installed the transient cleaner plugin again and run it to clear expired transient – no success and then to clear all transients – no success… The theme shows as 3.4.6 in the theme update tab with “no update required” showing.

I’ll go and update again via FTP but can you please advise / be aware that this is still not working as it should.
Thanks
Hugues
