Description

Enable auto config backup from the menu after entering (any) password, save, then disable (uncheck) "Enable ACB" and save on settings tab. Go to restore tab and enter a device key from different system and click submit. Backups are visible from device which key originated, "Restore this revision" and "show info" buttons do not produce desired effect. Attempting to restore produces the following output, we have identified that the initial SHA256 value in the latter part of the returned error is consistent across devices
<SHA256 values do not match, cannot restore. 116b898ea650a7cb25b3822c3709051ae25d27ce320b5bb8cab6a9e002b87860>

It just can't decrypt the config because it isn't using the right encryption key. If you set the correct key then you can view and restore from the other system. Though the error checking isn't reporting that properly, so it could be improved there.

I have a fix.

that looks better, when I do the same thing I get the following now with that patch applied to 23.01
__
The following input errors were detected:

Could not decrypt config.xml. Check the encryption key and try again: Could not decrypt. Different encryption key?__
