During the lockdown here in France Amazon was forced to close some warehouses and filfillment centers under pressure from unions (among other pressures, of course). It was big news for a week or so, and deliveries seemed to pause briefly before being picked up from German warehouses, too. After a week or so we started getting our deliveries again, usually with an extra day of delay because it was being fulfilled from Germany.
I suspect they will eventually do a deal with the Swedish unions but that, in the meantime, trucking things in from Germany will allow them to become established.
