Cannot upload renewed Apple APNS Certificate

Hi
I just received an email that my Apple Push Certificate is going to expire. I followed the steps to get a renewed certificate from Apple, but I cannot complete the last step - when I try to upload it to Prey it gives me a red ‘Error, invalid file’ message.
Please help!

Same problem here on iPhone13 Pro. Renewal expires tomorrow and I’m hitting that wall.

Question: does a certificate need to be uploaded for each device on an account? Or is one certificate sufficient to cover all devices? I’m on a free account. I successfully uploaded a certificate from my laptop but when I try to do so from the iPhone it fails.

iOS 15.6.1
Prey 2.1.11

And (since I am a new user and am restricted to one attachment per post)

And lastly

Well, I am completely confused. I can’t tell with any certainty what the status of Prey on my iPhone is.

I guess I’ll just wait for someone to chime in with something helpful.

when trying to renew the certificate for MBP 2021 this is the error at the apple site.
