Hi,
Sorry about this!
Regarding the certificate things. Did you get any warnings printed out to you? Like We do not have some...
(I suspect an issue is a switch over to assuming that your machine provides the teamID rather than ours)
Two plans of attack: (be sure to be on latest version of exp).
You can delete your two certs & provisioning profile from developer.apple.com and then run exp build:ios -c and let it create all certs again. With regards to the push one: see this comment: Build for iOS suddenly prompting for credentials - #19 by ide
Or you can run exp build:ios -c and provide the files from the result of exp fetch:ios:certs.
