Dropbox and Hazel

I read, try, and despair. Hazel has not been working with Dropbox on both my macs for a whole year now. Files in my Action folder, from which they are supposed to be sent to other folders also within my Dropbox local umbrella,are well over 15,000. And it used to work extremely well.
I give up with all this smartsync business. So my question is, where would you head and be SURE Hazel will work? Google Drive? Onedrive? I am on MacOs Catalina on both iMac and Macbook Pro.
Any personal experiences are welcome, and I will leave Dropbox and its recurring messages " This file is offline, Rules will start running when it is online again".
Thanks
