Syncing errors - how to resolve

[mcb1823]

I have 10 photos that I get a sync error between LR classic and Lightroom mobile.  When I go into preferences, lightroom sync I can see the photo that won't sync in Lightroom mobile. These photos are not critical and I don't need to keep them if the solution is to delete them from lightroom mobile.  I just want to get rid of the sync error in Lightroom Classic.  Any ideas on how to resolve?

I do have exactly the same error for 128 photos. I do not care about those photos. But no way to get rid of them.

I am living with this cpu consuming issue since the beginning. Please Adobe do something for us.

I called the Adobe help desk and the agent was able to resolve it remotely.  It was not a simple fix.  Contact Adobe support.
