Cashout offer vanished?

Placed a live bet on a soccer match last night and had a cashout option showing during halftime, but when I checked again late second half it just disappeared without any explanation. I didn’t make any other bets or mess with anything. Just kept checking back and suddenly the cashout button was totally gone, not even grayed out. Is this just normal risk control stuff? I didn’t see any crazy swings in the match, and the odds didn't drastically change until stoppage time.

Do you guys see this often or is it some glitchy nonsense? Feels like it happens way more often on less popular leagues for me. Not sure if I should get used to it or if I should be bothering support every time. Curious what everyone’s experience is, especially the folks betting live or on weird markets.
