I am facing same issue.. My application of PR approved and got COPR document number too. On portal ECOPR is not available… called technical support team and they said.. may be agent forgot to upload your document and it could be a technical issue.. They hold my call for 3 minutes and said they send message to IRCC officer and wants me to wait.. btw my dependent got his COPR already from same portal. Lemme know if there is any lead..
