It has taken a bit longer than the company expected but if you have a Mobvoi Ticwatch E or S model, you should have your Wear OS update that brings Android Oreo available. The company, in a recent post in their forums, indicates that 100% of devices should have the update now available and installed (or ready to install).
Originally the company had indicated that the update would roll out in March of this year but “Due to unexpected circumstances” the updates were delayed. The company then began rolling out the update early last week with the 100% mark for all devices hit on May 16th.
I can confirm that my Mobvoi Ticwatch E has been updated.
