Raid invites

Ive been trying to join raids since yesterday and they’re either not working or im not receiving a raid invite but I receive a friend request. I know servers have been messed up in my area due to recent bad thunderstorms but I’m not sure why this keeps happening and why it’s so consistent. I’ve been trying to do the lake trio raids since yesterday and this is a persistent issue and I don’t feel like the host is always at fault
