Very show synchronization for Gmail

Initial setup
1

I just migrated from Postbox and see trouble as unusable mail client for my gmail and google domain mail.
It’s very very slow synchronization for All Mail folder. It’s doing 4 hours+ and still in progress (while I write this Topic).
Yes, this is account with many many years mail history (from year when gmail appear). But no one other mail client didn’t have that problem.

No problems with hardware (Macbook Pro M3 Max) or network (all same accounts good works on Postbox).
eM Client version: 10.1.4393 (53e00e0)

It will take some time to complete the initial sync as all the data needs to be cached from the server. Google will also throttle the connection after some time, so you won’t get the full download speed possible.
