Not leveling to mythic despite winning last diamond match
I reached the penultimate pip in Diamond 1 ranked play today and upon winning did not level to mythic. I repeated this 3 times and no dice. My daily win counter also stopped advancing for each win at the penultimate pip. I closed and reopened the game, no change. I "repaired" the game file, no change.
I opened the game on my tablet. No change. I played another hand and lost, it reduced my level. Upon winning again I regained my pip and had the win count against daily. upon winning again, still no level into mythic, still nor recording the win for daily.
Upon the win that should be letting me level to mythic I get a "victor" display, but no avatar (or diamond rank badge/ animation). I made sure I was in standard ranked for these wins.
After multiple wins that should have leveled me (and stuck at 14/15 recorded wins for the day), I switched to Standard. I played, won, and got credit for the 15th daily win. Switched back to standard ranked, won, no level to mythic.
Please resolve this issue so I can enter mythic having won the requisite number of Diamond matches.
