I'd be surprised if Samsung went 3 weeks without another beta update, especially with the amount of bugs that need fixing, I can't ever remember the 2nd beta updates taking longer than 2week.
it won;t be later than 2wks.
In those cases where beta programs are not fully launched, Samsung always appears unpredictable.
996B army here, on Beta 2 and somehow managed to successfully enroll for the beta all while sideloaded.
Don't worry I am here hardcore beta user and will stay on it. Never Downgrade is my motto, hahahahha! Beta 2 has been great to me, Beta 3 looks very promising according to all inside information on twitter and internet.
Yes, i will stay on unrooted beta for next updates, when is available beta 2 i will share download link again.
