Subscription seemed confusing

I have 2 workspaces - on the one I applied the discount (which I initially thought would be applicable to both workspaces) It’s not clear from the pricing plans whether multiple workspaces are included or not. This morning when I tried to access my other workspace it said that the subscription expired. I could then see that 2x subscriptions were applied. I assumed the Discord discount could also apply to the other workspace. I signed up for the pro plan but before I could enter a discount code it automatically subscribed me to it. When I looked on my subscriptions it reflected I have 2 subscriptions active and a third will be charged “backdated” on my next biling date .In other words charged 1x for Sept to Oct + 2x Oct onwards when the discount period ends. For now I have cancelled subscription; but keen to re-enable.
