I have just returned from testing Pix4D Capture at some remote locations in the Amazon rainforest.
Separate to the issue of offline maps, Pix4D Capture did randomly want to connect to verify the account.
Initially, it worked fine, and then started to request a username and password, which would not work without a connection, and hence the app was inaccessible.
Once we travelled to where there was internet availability, logged in, and returned, it was working ok for a while, but then randomly requested a username and password again, again blocking access to the app.
It’s quite frustrating to travel to a remote location for mapping and then finding the app is not working because of the internet requirement!
