Natures calling event

When trying to claim rewards from natures calling event (Echoes from the cave) it would not allow me and stated that an “online connection is required. Please go online to save your Event progress and receive rewards.” However my console is online. Ive tried this at on two different consoles in different houses and this still appears. I know Xbox users and playstation users that are finding the same problem. Decided to wait and see if this would get fixed. A couple days later it hasn’t been fixed and had deleted my progress from the previous quest meaning i have to re-earn all of it and claim previous rewards that i had claimed days ago. Still the same problem is arising where I’m being told that i am not online despite having a connection. Hoping this will be quickly fixed as i find this very frustrating.
