I’ve extended my license via the webpage (before it expired) but so far on one device at least it’s saying it’s expired (none of the devices are in my control - family members). I think this, or something similar happened last year to me but i can’t find my post.
Does one need to manually update this license number for an extension? The instructions in the email seem to be for a new license (i’m renewing, not activating):
To activate a commerical or personal license, go to the Backup page in Duplicacy
Web Edition, click the link next to the ‘localhost’ label, and then you’ll be
able to enter the license code.
Cheers.
