All the posts in this sub-forum seem to be about problems getting the beta in the first place.
Has anyone actually got it?
I recieved it 10 seconds after i enrolled , TA-1033
TA-1033 UK Sim free , BT network.
Same problem here with my TA-1021 DS (Dual Sim).
Country : Roumania (EU).
I didn't even get second security patch for november and the last one for December via OTA, so i downloaded/installed them manually in order to receive today Android 8 beta,but with no luck.
@Anna please report this issues to your superiors,i really want to test android 8 beta,i tryied even factory reset + without sim to check for update but no luck.
Restart the phone and turned off mobile data, did the trick for me.
