This is...not possible. You are within range of 2-4 South American provinces even without the 25% you gain from Portuguese ideas (although I do think it requires the 50% from Exploration). I know this for a fact because I frequently steal Portugal's territory from them, and thereby have sufficient range to land in SA with Exploration's 50%.I have researched the two colonial range ideas from exploration as Portugal. Have colonised Rio de Oro and Arguin, but still unable to send colonists to the Americas. WHY and how to overcome?
Now if your question is about colonizing North America and the Caribbean, then the answer is that you're going to have to 1) wait for diplo tech 7 or 2) establish a colony where you can reach, wait for it to become a city, and core it, in order to extend your colonial range sufficiently to reach your targets. (Another good option-and faster to boot-is stealing a province from the natives that is near your colony or adjacent to it, and coring that.)
In case you've overlooked it-you will have to recall the colonists you've sent to those colonies, in order to establish new ones. (The colonies will remain, and continue to grow.) A simple thing, perhaps, but I'm honestly not sure how you're having the problem you're having, so I'm looking at all possibilities.
That's new to me-I wasn't aware clicking on the flag in ledger was ever disabled.What do you mean?
If hostile relations; I can't access their diplopage by clicking on their flag in the ledgerpage.
