You will not be able to add additional members (if the maximum limit is reached) but you will retain your existing members unless you remove them.

1. Owners can only add the maximum number of members per their current membership level.
   In January, owner A was at the Hero level and only added 2 members, but in February his membership level dropped to the Junior level. In this scenario, he will not be able to add more than 2 members (the maximum number of members for the Junior level) to his Family Wallet.
2. Owners whose membership level has dropped can retain their existing members in Family Wallet.
   In January, owner B was at the Hero level and successfully added 5 members, but in February, he dropped to the Explorer/Junior level. In this scenario, he will retain the 5 members in his Family Wallet unless he removes them. If they are removed, they can only be re-added once he levels up and increase the maximum number of seats. If he removes any member while exceeding the maximum number of seats allowed for his tier, a warning will appear.
