First question, does it create logs and second question, where are they? I’m sure I found them before… I searched here but the search was too general.
Yes!
Config files and setup backups:
C:\Users\%USER_ID%\AppData\Roaming\Nextcloud\*
Logfiles:
C:\Users\%USER_ID%\AppData\Roaming\Nextcloud\logs\*
Much and good luck,

Smashing thanks - should have thought to look there.
