Start reading the feedback and act on it
It does not seem like Microsoft really uses this feedback. Remember that a fraction of users really give feedback - most just change program or lives with the software unhappey. E.g. international users (yes there are people outside the US) cannot write correctly in OneNote due to autocapitalizaion of sentences and "I". https://onenote.uservoice.com/forums/327180-onenote-for-ipad-iphone/suggestions/13623291-option-to-disable-autocorrect?page=2&per_page=20
The fact that the top 3 requested features date back to 2015 shows that something is wrong and it needs to be fixed immediately.
If nothing is being done on the iPad and iPhone forum should the OneNote Twitter account be bombarded with our requests instead so something is finally done?
Will our voices be heard better on Twitter than here?
