This is already a post where other users could have voted in support or commented in more detail if they agreed with you. Granted not every user reads these posts, but enough do that you should have had some reaction if this was a general problem. All of the responses - including me - are from other users, and we don't have access to raise this generally, but that's what Support teams are for. They collect details of what's bugging individual users and pass that on to developers, as well as trying to help individuals work through why their own experience is not as good as it should be.
If you haven't already gathered - Support got buried months ago when multiple changes to the software caused a LOT of enquiries in a short time. They will get back to you, but it will take as long as it takes... be patient!
Meantime have a look at your local system - do you have plenty of free storage space? Enough free memory? Is there any competition for your internet access (are there several devices connecting via your current link)? Do you use a firewall? VPN? Any number of things could be slowing your system down...
