How many you work on the same project on 2 different MACs?
Senarioโฆ One MacBook Pro (traveling device) and one iMac (office).
Are they any instructions whether documentation or video to show the procedures?
Note: currently Assets are on one device. Love to move them all online, but that would be an enormous task.
And what about to have the Assets on an external SSDโฆ I do this often.
So when you travel, I assume you must have the SSD with you.
Yes so you have always the assets you are working on
You can use the export Generate Package feature. Then just use your project from that folder. It will bring all your assets together in that folder.
Keep it on a cloud solution like Dropbox, ICloud etc, access from anywhere.
I am going to try this again, but you know what happened the last time.
I was sure we had this conversation before. I donโt remember you trying it though.
We can walk though it on the web chat. Thats what itโs for, helping each other out. Although we dont talk about Blocs much 
Yeah Blocs was exporting all kinds of strange characters with many images.
Oh thats right, it rings a bell, but I canโt recall all the details. I assume support got you nowhere.
