You may be aware the prior version of the iOS mobile app had a couple of bugs that would cause it to crash if your exchange had either no messages, offers or requests listed in the news area. That’s all been fixed, and Apple has approved the current version here (after taking the survey): https://pennstate.qualtrics.com/SE/?SID=SV_bxbaduKSMeyJ68B or search the Apple or Android stores for hOurworld. PARC needs around fifty more respondents to take the survey.
The apps are now configured to self update. So to be sure, uninstall your old version manually, then download and install the new version. Henceforth it will auto update itself if needed.
A version two is in the pipeline. Let us know if you have suggestions, problems or feedback at email@example.com
