I thought I had purchased it a few years ago, but I do not have pro on my computer or in my Google Drive. How do I find it?
The version I have on the computer is the free one, which is spontaneously generating the following message: "Diary not synced. A newer version. A newer state of the diary is available on the cloud."
On my phone Samsung S21, no matter what I click on I do not get an option to buy. If I try to sync (which I thought was a pro feature) I get an "Error while syncing diary" message.
