Yup. Any money you get on a day has to sit in the limbo for 30 days. e.g. Money you get on July 1st becomes available on July 31st... Money you get on July 2nd becomes available on Aug 1st, etc.
In addition, Apple/Google store fees will be taken out of your current balance before it becomes available. Which is really confusing IMO even with the new explanation they added. Hoping the staff will make that less confusing in the future.
