Samsung has corrected the issue with the Oreo update for the Galaxy S8 and S8+ and the rollout has resumed.
The new firmware brings the software version up to G950FXXU1CRB7 for the S8 and G955XXU1CRB7 for the S8+. The update weighs 530MB for users who updated their phones before the rollout was suspended, those who haven't are looking at a larger download.
