P: Drag and drop GPS tagging not working. Right click on map also not working

Yes. I have tried them.

At least in my case (and my case is the original from 2 years ago!) the root cause is not a corruption issue. It is photos that Address Lookup can't handle. Photos off-shore, for example. Or sometimes, just really far from a road. 

I have identified with Adobe that these photos break GPS tagging due to Address Lookup hanging on them. And yes, the catalog becomes corrupted. If I make a new catalog, and exclude these photos, it works again. Of course, that's a huge pain in the ass, because I never know which photo has broken the catalog. But inevitably, another photo breaks it again. And we start over. 

It's a known issue. it's solvable. They just don't care. 

Yes.

Did you try the steps I explained previously ? Are you sure your catalog is not corrupt ? To check, just try to import it in a new catalog first.

Did you try the steps I explained in this thread ? Are you successfull when you try to import your current catalog ? In other words, are you sure it is not corrupt ?

Correct.

I went all the way through troubleshooting with Adobe customer service agents (including seniors). After three or four weeks of emails, calls, uploading catalogs, screen grabs and video captures of the fault they called me to say they can’t fix the fault and it will be resolved in the next release

Hello......????

I have fixed this with a new catalog too. But the problem will come back. It's not fixed. And they won't fix it. 

The issue is that LR always populates place names using Address Lookup when you use the GPS tagging feature. Sometimes that gets stuck, and it crashes GPS tagging. Unfortunately, you can't disable the Address Lookup feature that is causing the issue.

A new catalog can help, because it might not include the photos that don't work with Address Lookup, but once those photos are back it crashes again.

Adobe knows about the issue and has for a long time, I spent many hours with their engineers reproducing it. But they won't fix it. They don't care. 

Find a new product. They don't care about us.
