I have "Yes" selected for "Did the taxpayer electronically sign the T183". When I try to enter the date and timestamp on the T183 from the e-signature, the date disappears as soon as I tab off or click elsewhere on the return. Timestamp stays as entered. 

Can't use prepare sign-off on the date and EFILE, I get an EFILE error. 

CRA Result Code: 132 : Missing or Incomplete Information.
The Canada Revenue Agency was unable to process your return. The transmission contains invalid or missing data: 
EFILE Identification Field(s)
T183 Electronic Signature Indicator
T183 Electronic Signature Date
T183 Electronic Signature Time
Please make the necessary corrections and try again.

Anyone else having this issue? 

Can't use the client explorer build EFILE option now either, since we have to manually enter the date and time on the T183 for every return e-signed. A lot of extra work - and currently not working at all!
