Difficulty logging on

Have you installed the offline maps?

When you say the problem occurs "lately", the implication is that previously it worked properly and now it doesn't. Is that correct? If so, what changes might you have done since it last worked properly? Are you using the correct log-on credentials in Traveller? Eg have you changed your account password or email but not updated it in Traveller?

BTW, the app's name is Traveller, made by a company called ExplorOz (spelled with only one "e".)

Cheers

You say you have just started a trip. Has this problem begun since you started the trip?
Are you connected to the internet?
Have you downloaded the Offline Maps? If so have you ticked the Offline Maps in Map Layers (top right of screen)

Try reading the manual, pretty obvious what the issue is , Dick above has it sussed.

Hi Ewan,
I'm about to drive out the door for a trip - all packed. Auto replies are on the Help Desk so thought I'd quickly pop in a response to you here....
Your post is titled "logging on" - is that the issue? Ie entering your email/password into the User Account? If so you must be online - and I query why you are logged off in the first place?
You should never log off from the user account as this will cause problems. Keep your details logged in and when you close the app, just use the normal method to close an app (ie. tap the 3 vertical lines at bottom left of your device where you will then see all open apps and swipe the minimised app away) but do not log off. If you log off, you cannot log back in when offline and by logging off you will delete all your Places/Treks databaase (for IP security reasons) so then you are left with no data offline and no way of getting it back until online again.
DON'T LOG OFF

I too, have experienced this same issue. Mainly on my android head unit. It for a while would still load with the error message over the top, until you click ok. Then it would crash the app, I’d have to force quit the app a few times before it would load. However since the last update it just sits on the ExplorOz screen with that error. I expect I will have to uninstall and reinstall and download all maps again. Really painful as on the road and have low mobile reception.
Running on Android 10, external storage (16GB thumb), quad core T3.

So, Ewan, is it fixed?
