I've had this problem just recently. Sequence of events:
1) Click "Watch Ad" to undo a turn, unlock a unit, or earn 5 credits
2) Dialogue box appears, loads ad
3) Ad screen loads but goes straight to the end of the ad; no videos, no animation, no countdown; only option is the hit the "X" in the upper right
4) Return to the game but NOTHING has changed
I discovered a work around for undo a turn: completely exit and close the game, then reopen, the turn will be back at the beginning. That trick doesn't work for unlocking a unit or earning 5 credits.
Anyone else having this problem? Any fix? Its really frustrating.
If it helps. from the "About" screen:
- Uniwar 1.12.11
- LibGDX 1.9.6
And my device:
- Samsung SGH l747
- Android Version 4.4.2
