On 28.12.2018 I updated on iMac 10.14.2 from Enpass 5.6.11 to Enpass 6.0.0.
Then I stated that the there is no more synchronisation to iCloud Drive.
Disabling and enabling the iCloud Drive brought only two new files in the Enpass folder of iCloud Drive.
Recording an example login in Enpass and a new synchronisation does not change the time stamp of one of the above files.
That means none of these files are including the example login.
Therefore, I still wait to upgrade Enpass on my iPad in order not to lose all my passwords.
The Enpass people should finalize their job and carry out a thorough testing first!! Thank you.
