Intune sluggishness to be expected?

I’ve used a lot of cloud based platforms over the years and have been generally impressed with their responsiveness and overall usefulness, but I’ve recently started using Intune and am kind of at a loss in understanding its sluggishness. In particular, syncing, last check-in, app deployment, diagnostics collection, policy updates and deployment rings. Which, now that I write it all out, is just about everything we use it for (so far, still early on in deployment). Is it normal to not have a response on most of these items from devices that are connected to our network and the internet, for 1/2 hour to sometimes hours? I’m finding it incredibly difficult to implement much of anything, and even more difficult to diagnose issues when I have to wait for what seems like an eternity for anything to happen. I realize I can restart the Intune Management Extension service on the divide and generally get things to sync, but that kind of defeats the purpose of remote (unattended) management. Not to mention, I’m of the belief it should really just work better than…barely? This is more of a vent than a general discussion, I suppose, but I’d like to hear of any similar frustrations, and especially any success stories. Or if anyone “in the know” knows if Microsoft has any plans to improve these matters?
