Was glad to be using iphone again. Because most of my data is still on icloud. When i restored the backup it seemed that I could not get the wordpress to publish a post. I tried updating jetpack and the other plugins on the wordpress page didn’t work. I also tried logging in from the wordpress app. For me the solution seems to be this. Go to the settings of your wordpress app and enter your password. It seems that after reinstalling from icloud it needs your password again.
