My Edge 520 automatically updated itself to version 5.30, and now it wouldn't accept manual wheel size. I have a PowerTap GS hub power meter, and when I specified 1924mm for my 650c wheel circumference, it reverted back to 2096mm everytime I backed out to save. I even removed the power meter and re-added it to no avail. Any ideas? This issue never occurred with version 5.20.
