It would be nice to be able to submit errors on the Web App.
weekly bump of unanswered posts in hopes of getting a response
Martin, thanks for your request. Unfortunately, it's unclear to me what type of errors you are wanting the ability to submit in the web app. If you are requesting a feature to submit typo reports, like you can in Desktop and Mobile, go ahead and give this feedback post a vote.
Otherwise, please feel free to submit new feedback on https://feedback.logos.com/boards/logos-web-app or provide more details for me here. Thanks!
