For the last few firmware updates, you may find that your affiliate reverts back to it's factory setting when you sync your Kobo. You can set a string in the Kobo eReader.conf file to prevent this. Under the [ApplicationPreferences] heading, you can add:
Code:
LastAffiliateSyncTime=@Variant(\0\0\0\x10\0%\x94h\x3!>i\x2)
This will keep the affiliate check from happening for ~8.5 years.
See the
FNAC affiliation reset on newer firmware (4.23.15548, maybe for more on this issue.
