Off to Nairobi in 5 days (I may have mentioned this elsewhere ) I applied for my e-visa a few weeks ago and had to re-enter payment details. Got receipt for payment the second time and visa itself the next day. All good. I was a little annoyed to see two fees debited from my credit card when I checked the next day but 3 days leter when I looked again there had been 3 applicaton fees taken and 2 refunds made! Seems a little unreliable but it gets sorted in the end.
Will post if anything at the airport has changed from the experience of @offshorebirder in January.
