Same issue for me as well yesterday. Tried uninstall/reinstall to ensure there wasn't something strange going on. This happened for me with both Yorian and Kergua decks. I use the untapped plugin which showed my sideboarding correctly.
Then a game with Bant Yoiran, I had sided in Dovin's Veto and didn't see it in the list with a Tamio activation. Sadness.
