I redownloaded the application from the Appstore several times, but still didn’t work… so frustrated
hi @Roooonan ,
Which phone and OS are you using?
From your title of Sign up, I suppose you are trying to register.
As an alternative, can you register on console.particle.io ?
Let us know if you encounter any difficulties.
Thanks for your reply! I’m using iphone12 pro with IOS 14.8. I have successfully signed up and signed in on my friends’ iPhone12, but back to my phone, the particle mobile app still reminded me “Cannot sign in - Unknown error occurred” . What should I do?
