Sometimes Bend shows an "Update Required" message asking you to update to the latest version. If your device won't let you update, it's usually something on the device side. Here's what to check.
Update your device's software
The latest version of Bend may need a newer version of your phone's operating system. Update your iOS or Android software, then try updating Bend again.
Free up some storage
If your device is low on space, the store may not be able to install the update. Free up some storage and try again.
Then update Bend
Once that's sorted, update Bend from the App Store or Play Store.
