“I am using Zapier to send an ‘Update Widget’ command. Zapier confirms the action is a success and that the data is being sent. My widget content is configured to display [[input0]]. However, the widget on my Home Screen never updates and continues to show the placeholder text [[input0]]. I have checked my Background App Refresh settings and restarted my phone.”
I don’t see a Zapier app in the app store for iOS. I suspect that there is key information missing from your post.
You might also want to rename your topic to describe the issue and not your need for help … which describes most topics on the forum.
