"No friends online" Eternal Collection for Switch

A friend and I bought Diablo 3: Eternal Collection for the Switch and an online subscription in hopes to play together but the game refuses to acknowledge that we are online. We cannot send invite to each other as both our friend lists just say “No friends online”. We have added each other as friends on the switch, we have checked the region settings and we both made sure that we were connected but still no success. We also tried closing the game application and restarting it but the friend list still showed no friends online
