@bacon can i get some help regarding this issue?

Hey @r_mhjn,

Sorry for the delay in response here. I’ll start off by asking if any you’ve discovered any new information that would be helpful in debugging this?

Also, could you please share the name of the Expo account the project is under and the slug value?


hey no i could not find anything to debug this issue, the name of expo account is r_mhjn and slug is DataAnnotator…i was not able to add a jks file created by me, so after alot of tries i settled to let expo handle the thing, but will be good if i can add my own jks file…

Thanks alot for the help.
