Hi, I am wondering why on the app store the default sorting on review section is "sort by Most Helpful" rather than the latest review? On this particular concern also would like to know the algorithm behind the most helpful? Since we saw that the most helpful review was comment from 5 years ago in which we have fixed so much things and the related reviews seems irrelevant.
Default Review Sorting
Don't read the reviews; for reasons like the one you describe, reading your own app's App Store reviews will drive you MAD.
If you really feel that you need to know what people are saying about your app, pay someone else to do it for you and write a summary.
I'm not joking; this is serious advice, based on 15 years publishing apps and trying to stay sane.
