Hi,
to your questions:
Windows PC App
don't fully understand your question. To ensure that the master pwd is everywhere the same, I changed it on all devices to the same pwd, even though all devices are syncing to one and the same WebDAV location - quite strange approach, but finally it worked like this ...
yes, all the same
yes, to a location on my WebDAV
all the latest versions, downloaded from your webpage
Finally it seems to work. I deinstalled the Windows App completely, re-installed it and imported the wallet version from the WebDav. Quite an effort. But it seems to work at the moment. Keep fingers crossed.
Another topic: I imported my wallet from 1Password. Quite a lot of 'unvisible' and useless fields came a long with it. Example: one field called "Webpage". Second field called "url". Both are visible in Enpass and have the same content. Any hint to clean such duplications up? Thanks!
