Ok, looks like I already could hide the alert window. And now I know that it needed 1 Credit, leaving me with 999 and 1050 being needed for seven lucky potions. 2 more Credits for claiming the potion purchase and opening the pack.
If you came here for taking the airdrop, consider buying 1053 Credits, because 1000 is the minimum purchase and you can not buy three potions, but minimum for 1000 Credits. 150 per potion making it 1050 Credits + 3 for making transactions without ETH on the B3 EVM.
Here is my loot from the airdrop:
Hey @anjanida, apology for the delay. We're working on a fix to solve the "waiting" issue. Congrats on the pack opening!
