After month of troubleshooting and 0 help from Edge developers here are my findings:
Regarding #1 bug nothing changed and I can't do anything. Workspaces have to understand that there are 200 then JAVASCRIPT redirect from Facebook and Instagram (maybe other sites too).
Regarding #4 bug with problems to access your workspaces you have to close your account and create new one, sorry. Problem is on Microsoft servers. Sometimes you might access your workspaces from other browser or computer but it is random and you will loose access eventually. If you have this in your edge://workspaces-internals :
Spaces Event: EdgeFluidCSPStorageHelper failed at OnGetContainerListComplete
{ "Date": "0", "ErrorCode": -102, "PrimaryError": 17, "SecondaryError": 37 }
Spaces Event: WorkspaceManager: Failed to initialize Fluid Error code:46 tag:-41
Spaces Event: Fluid Manager Process Failed
"Failed to initialize Fluid"
Just run! Microsoft won't help you and won't send you a backup. If you want to feel safe create new account and use Tab Session Manager that will save sessions everytime you close browser or window.
Regarding #3 bug I have no idea why Workspaces can stop sync without a notice. Sometimes it can stop sync, but there will be red dot.
And most important #4 bug:
It appers that Workspaces is poorly written and highly abuses Chromium sync (made for syncing bookmarks, settings, history, not for workspaces) with LevelDB in Sync Data folder. Opening any Workspace start up to 3000 I/O writes delta and 2000 I/O reads delta, writes to disk are also high making hundreds of gigabytes a day. It contributes to SSD wear! It doesn't freeze a system and there are resources left to run even another browser, but such I/Os make browser unresponsive. I'm sure it's because workspaces because I opened same set of tabs without workspaces and there was no problem and I also saw that when I disconnect form the Internet or block IPs connecting with Edge - it's unfrozen - workspaces can't sync and LevelDB writes go low. Workspaces make LevelDB tables with many keys and long values of favicons and updates fast. LevelDB can't keep up so it freezes the browser.
Can anyone except developers do something about it? Only idea I think is to move Sync Data folder to Ramdisk, I have to test it. If it fails then workspaces are just useless, full of bugs crap with no support.
