Yes they do!
The old problem (A) has been improved to become two problems (A+B).
The symptoms are the same, no level-up though the XPs in display have been exceeded.
Solution to A: collect XPs till the next level, suffering a delay of a few days to a few months, but gaining the experience that changes are scarce,
Solution to B: Play one game, one shot or whatnots - just a nuisance and a remainder that the game calculations may be questionable (including the accounting as we learned after the last clash).
