I work self employed as an administrator for another busines.
They use OneDrive.
Every, single, tedious time I want to look at anything, I have to sign in to microsoft. This can be 20 or 30 times a day (don't bother with keep me signed it, as it simply doesn't work).
As has already been said, why would you have a file in the cloud, that when deleted, automatically wipes it on every other device? It's knuckle-dragingly cretinous.
Here's another single-cell brain wave example - one of many: There is a password protected spreadsheet for the company I deal with in their OneDrive that I have shared file access to. It has a list of over 200 passwords, which I need to access regularly. When Microsoft decide at random that I need to change my password for Microsoft / OneDrive, it means that because I can't then log in at that point, I cannot locate the current password (you have to put that in first, then enter your new password twice), so I have to save a seperate password protected spreadsheet on my pc somewhere, or write it down, as otherwise, I'm screwed. That means I have to frequently cross reference the password spreasdsheats to ensure both are correct and up to date. It's totally ill thought-through. EXCEPT, that it isn't; they know EXACTLY what they are doing; They can't be that stupid. It's a data-raping exercise as per all the IT companies these days.
For the Trekies out there: It makes me wish for one of those planets where the populous appear to live simple rural lives of peace, tranquilty and harmony, and it turns out they were super-advanced and realised that all high-tech did, was ruin their lives. Considering a dumb phone yet???
Unfortunately, I am locked into this spiral of despair- for now - though the company I work with are beginning to realise just how costly this facility has become in terms of lost time/constant issues and dreadful functionality.
