Syncing issues are getting out of hand

Syncing problems have reached a critical point, rendering Lightroom almost unusable as a cross-device application. I find myself spending more time troubleshooting syncing issues than actually editing. The frustrating cycle repeats weekly, and I've reached a breaking point.

For a few days, syncing appears to work, I get a green checkmark in LrC, even though many images, when I try to open them in LR, don't have any edits synced. That became a minor issue. The main issue is that after a few days of working, when I import new images, even though sometimes as little as 5 images, the syncing gets stuck for days! Every time I', naive enough to think that this time it will work on its own. It doesn't. After a few days I get fed up and I start pausing/unpausing, opening/closing Lightroom Classic and after a while of doing this, the syncing gets unstuck and finishes. Sometimes I have to do this for a long time. Then it appears to work for a couple of days and happens all over again.

I've attempted the "Rebuild Sync Data" process multiple times, a task that took over a week to complete. Regrettably, it provided no resolution. In a more drastic measure, I deleted all data from LR and LR mobile, initiating a fresh import. Yet, this, too, failed to alleviate the syncing issues.

Is there any additional step I can take, or is this a predicament only solvable by Adobe?
