Microsoft Edge Dev Sync Issues on Linux/Debian/Ubuntu

First, I think that it would be helpful if you (1) let us know the Dev version you are using, and (2) explain the nature of the issues you are encountering with sync. That might help us to replicate/test the issues you are encountering.

Second, if you can, it might be helpful to submit Feedback to Microsoft so that Microsoft's technical staff can evaluate the issue.

I do not sync extensively (syncing favorites, passwords, settings, personal information, and extensions, but not history, open tabs or collections), but I've not encountered syncing issues involving my two Linux computers, which are synced with two Windows computers, an iPhone 2020SE and an Android tablet**. I don't know if that is typical or not at this point.
