OneDrive corrupts computer storage

OneDrive has proven to be a frustrating and aggravating unreliable piece of junk.. 

Example 1:

1. Edited an Excel file.
2. Saved file to Documents/(subfolder chain)/<filename>
3. Closed Excel.
4. Use Edge to access Gmail account.
5. Created a new message
6. Selected to attach a file
7. Browsed to Documents/(subfolder chain)/<filename>
8. Selected Insert
9. Sent Email
10. Checked sent messages folder.
11. Opened the sent Email
12. Opened the attached Excel file
13. The file it attached was an old version!!!!!!!!!!!!!!!
14. Using File browser, Opened <filename> following Documents/(subfolder chain)/<filename>
    1. It is the updated version of the file.
15. Using File browser, Opened <filename> following the path OneDrive/Documents/(subfolder chain)/<filename> 
    1. It is the updated version of the file.
16. Went back to Gmail and created a new Email
17. Selected to attach a file
18. Browsed to Documents/(subfolder chain)/<filename>
19. Attached <filename>
20. Double clicked the attachment to open file
21. The file it attached was an old version!!!!!!!!!!!!!!

Why didn't OneDrive allow the local copy of the file to be physically updated when I saved it - at the time I saved it.????

Example 2:

1. With the computer off-line: open <filename>
2. Edit Filename.
3. Save filename
   1. Get warning message that computer is offline
4. Select to save the file, anyway.
5. do other things off line.
6. go online and handle other tasks
7. navigate to and open <filename> 
8. It is the unedited version of the file!!!!!!!!!!!!!!!!!!!
   1. Sidebar comes up saying excel has a temporary backup
   2. Why didn't OneDrive allow the local copy of the edited <filename> to be saved as commanded in the first place?
9. Open the temporary backup
   1. It is the edited version of the file
10. System REFUSES to save the backup file to <filename>

Again: OneDrive is a pain to use.  Working with documents is unreliable, you never know which version you are going to get.  When you use File Explorer to navigate to and open the file, it will show the correct version. However, when you select the file from other applications for it to be inserted, it pulls a previous version of the file.

What is physically written in the Local Copy is unreliable.
