Stuck on Downloading Messages from iCloud

I don’t seem to get any notifications about uploading or downloading messages...

10 days and counting here

I installed Mojave last night and still have the issue. 😟

every few days one of my Messages apps (either rMBP, iMac, and/or iPhone) will start "downloading Messages..." again for a bit (no real network activity) for some minutes or some hours, and nothing really changes.

Apple, once again, shows that they have lost control of their iCloud service many years ago, and just piled on one more problem after another on top of it.

both I and my almost 80 year old mother had our Apple ID's blocked recently, and were forced to reset our passwords (something my old mother had no idea how to do)...for me, it meant 2 days of inputting my new password, over and over again (why?!!), for my mother, who only has an iPhone, it has asked her about 15 times in the past 3 days to input her password , and it still does so when she tries to do anything (why??!!!).

it just shows me that Apple is unable to tame all of their connected services, starting with their Apple ID and "ending" with this new feature of Messages in iCloud...the fact is that iCloud has *never* worked reliably when attempting to sync Calendars, Contacts, Photos (in iPhoto or Photos), ... and now Messages...not for me or anyone I have helped to make the switch to Mac OS.

how many times have you seen your Contacts be doubled and tripled and ended up being afraid to sync your Contacts...same with your iPhotos library? at least to many of my friends and family this has happened over and over again.

and this is yet another issue they piled on top of it all.

there is something fundamentally wrong with Apple's iCloud infrastructure...hear me now, believe me later.
