Issues after Cross Progression is activated on your account? Check here first!

I am running into a problem when the Apex accounts where merged. Me and my sibling are under the same account and played on separate consoles and would play together with friends. We are wondering if their is any way that we can play at the same time with this account while the other is playing at the same time without starting a new account and losing all the progress we have sepertly accumulated over the past years. If you can help us that would be great thanks!
