I've got all the different Android versions they've ever released all downloaded onto an old Android tablet. I keep it specifically for the purpose of being able to access these older versions of s8 games, lol, normally I play on iOS.
Anyway, when I open the regular version of BS, I can see the Honey items that I've already purchased but there is no price listed; even though it has the sales banner I cannot purchase more.
If I open the Honey version of BS, I can see the items, their current sales prices, the sales banner but I can actually purchase more in this version:
As it's the weekend, we likely won't see a fix to this bug until Monday, that's if they see this as a bug at all. I'd suggest if you're on Android and really want to purchase any theme-specific items, you download the Honey Version though a mod will likely tell you this is not recommended, I've never had an issue accessing an older version in order to purchase specific items. I wouldn't recommend you try to actually play daily or do goals on the old version but a quick pop in to buy something...totally fine.
If you have further questions, feel free to PM me.
