Type of devices currently running on the Sync chain in question:
Windows, macOS, iOS, iPadOS
Additional Information:
Before, the tabs used to stay for a while. Like i’d still see tabs I had already reclaimed but the machine would still be there. And I don’t always remember there being a 10 device limit. Are they limiting the limits of sync due to storage? Could we host our own sync servers so users like me wouldn’t have to risk losing hundreds (maybe even thousands) due to forgetfulness?
