Bounty of Might soft-lock [Investigating]

I didn't see this one on the bug list.

Playing a Simic deck with Simic Ascendency and some adapt minions. I'm trying to test if Bounty of Might will reinforce Simic Ascendency.

My board
Sharktocrab (2)
Trollbred Guardian (2)

Supports:
Simic Ascendency

Opponent's board
Relentless Hunter

The play
On my turn, I match and cast only Bounty of Might.  On "NOT NOW/SELECT" pop up, I select my Trollbred Guardian and press "SELECT." Nothing happens, but Trollbred Guardian is highlighted with the white border. I tap on Sharktocrab and tap "SELECT." Nothing happens, but now both Trollbred Guardian and Sharktocrab are highlighted. Just for experimentation, I tap on the opponent's Relentless Hunter and tap "SELECT." Nothing happens, but now all three minions on the board are highlighted in white.

I tap on "NOT NOW." Nothing happens. Interestingly, if I repeat the above-described process, but tap "NOT NOW" each time instead of "SELECT," I get the same result. I cannot get the "NOT NOW/SELECT" pop up to close, thus my game is soft locked.

Battle Log
I still don't know if Bounty of Might reinforces Simic Ascendency -_-
I'll keep testing.
