i am unable to use the map editing features on my pc. Any advice?
What happens? You should be able to clone and select editing tools (even if the are shown as blank), e.g. the top second one is the paint tool.
I think thats how it works, I had issues with editing until I found out this cloning ability, I think its just a feature so original maps dont go corrupted or destroyed on your device, instead of tampering with default maps it gives you the ability to edit clones so we can mess with them and create more.
The most recent update on the desktop (and mobile betas) should make it more clear that you need to clone the standard map before editing them. And the missing tool icons have now been fixed.
