I was playing Asuza brawl deck. Opponent didn't have any effects that affect land playing or entering, since I had played multiple lands on my turn already (at least 3). When I went to play Asuza's Many Journeys, the effect "you may play an additional land" simply didn't happen. I couldn't play an additional land after that. I don't know what caused it, and sadly I didn't take an screenshot. There didn't seem to be any enchantment/aura blocking effects on the battlefield.

Some cards I had on the table that could've caused the issue:
Brood Astronomer (maybe the land card counts as played?)
Ashaya, Soul of the Wild (creatures are lands, so maybe that increased the played land count)
Titania, Gaea Incarnate (maybe the meld with Ashaya counts as a played land)
I had also scapeshifted for total of 13 lands and creature-lands.
