played this morning and now can't seem to connect due to some watercress error

They are aware that there is an increase in Watercress error messages. They’ve relayed some information to other users earlier today, stating that it had to do with too many play sessions open on an account. They confirmed that this only seems to be affecting XBOX players. If you have cross-save enabled and you have another platform, you can continue playing there. Otherwise, they may have a fix in the works and should have more information on it when they’re ready to discuss it.
