Apple has today released watchOS 7.3.1 for Apple Watch Series 5 and SE, reportedly to fix an issue that prevented the watch from charging when in Power Reserve mode.
As watchOS 7.3.1 is only available to select models to address a specific issue, our expectation is that it does not contain any accessibility changes for blind and low vision users; however, if you notice any changes, improvements or regressions in your own use of this release, please post a comment with your findings.
