No updates are ruining this app – Inbox Pro, for Outlook Review

This app was great a year or two ago. Unfortunately, it appears it may have been abandoned by the creator. There hasn't been an update in nearly a year. The technology and features produced by Apple and Microsoft has exceeded the capabilities of this app. For example,I find many attachments that previously opened no longer do so, the app is slowing down in opening emails, and calendar invites are not received by the person requesting one. I use this app because work doesn't allow push email to devices off our network. Inbox pro logs into web access, pulls the data, and displays in on your phone so it appears to look and function similar to outlook. Username and password information are stored so you just click the app and it checks new messages. A year ago I would have recommended this app to anybody who had similar network restrictions as me. Now, I say do not buy until an update is released to catch up with technology.
