Dor the life of me, I can’t figure out how to update iMessage apps? My App Store updates are clean and at zero, but in iMessage, the iMessage AppStore shows 14 updates when you clicks on the AppStore image in iMessage. Any suggestions?
iMessage apps update through the regular App Store when the corresponding app updates.
The badge that reads 14 is an indicator of how many iMessage apps have been updated but not used yet.
To get rid of it, you need to navigate to the More... area of the app drawer, then tap Edit and toggle on all of your iMessage apps. This should clear the red number. You can then toggle off the ones you don’t want.
Terrible design, I know. Hopefully this will change on a future update as it can be annoying.
