LightRoom while off line

Thanks for the advice, and how it should work in theory according to adobes guidelines unfortunately, that is not the case. Adobes Overseas Telephone Support is useless as they don't know their own product and the rules. After many calls now, non of the adviser had the foresight to offer me a solution to switch to yearly payment as you pointed out, this theoretically should solve the issue. Looking up my account, there seems to be no option for a yearly payment option. However, now being on the call with Adobe support, they tell me that even a yearly subscription does have only anywhere from 5 to 30 days of non-online use (directly contradicting what their website says) WTF. Interestingly they also tell me they have hidden terms and conditions they can't share which govern that particular section. I'm just recording the one-hour conversation with adobe as this may warrant a video it's incredible the BS I have been told by their team. I'm now talking to supervisors who are also baffled so stay tuned. So the latest now is that the grace period only applies if you fail a payment but has nothing to do with having no internet for a few weeks if your subscription is active, and that would fall under anywhere between 5-30 days. I'm recording the whole telephone call as it's quite incredible.

The Creative Cloud software verifies the account status on Adobe servers once a day. If the account is in good standing (that is, payment is up-to-date) when the last verification happens, the software status refreshes to run for at least 99 days offline.

The amount of data to check is so tiny, if you can teather the Mac to a cell (satellite) phone, you're set. 

I have seen some reports that suggest that changing the time zone on your computer triggers the Creative Cloud app to try and verify the license, so if you do not have an internet connection at that time, there may be a problem. That means you may be able to solve this by setting your computer to the new time zone before you leave (and while you still have internet), and then start the apps one more time. May be worth trying.

Yes I'm testing it now leaving the computer offline, I had that actually in several instances and never have seen a message where I could extend use after the first and only message that Adobe can't connect to the server. Just a lot of effort to go trough to ensure I can use a paid application in different geographical locations in the same country, again no other applications but Adobe have this issue. The day Affinity brings out something similar to Lightroom I'm leaving the Adobe train

The current policy is that annual subscribers can go up to 129 days without connecting to the Internet, while month-to-month subscribers can go up to 60 days:

There have been a few other reports here in the past year of people not being able to use LR while disconnected less than the maximum number of days.  

Before you travel again, you might try disconnecting your laptop from the Internet for 3 - 7 days and verify you can continue to use LR.  If you get errors, post back here with screenshots of the entire LR window, including the error messages.

no mate I can't organise my travel based on one application where often I go simply is no connection

Ok so you just need to concentrate on how to keep connected while traveling.

Do you have Adobe Creative Cloud application active on your travel laptop?

Sorry, you are correct, I can only use one computer at a time however, I can stay signed in tow two computers. I don't use my Laptop at home, so never try to open LightRoom on two machines at the same time. If I'm away I only use my laptop at home my Mac Studio

You stated “no, I don't sign out I can use Adobe on my Desktop at home and on my Laptop and I'm always signed in.”

You can have two units signed in, with one in use at any point in time. When I travel abroad my Desktop is signed in but the Computer at home is shut down.

Lightroom Classic is a single user application. You can have multiple Lr mobile apps running.

I believe when you reboot your laptop and LrC app if there is an internet connection it will verify your subscription, if you have the Creative Cloud application installed and running.

I usually open LrC using the Creative Cloud application.

When you boot the Creative Cloud app it will verify your subscription, so if you have access for a couple minutes then that will reset things.

Just a thought, do you make your payment monthly or annually?

If you pay annually you may have a better experience. When you pay monthly you have to be connected every 30 days, annually it's 90 days as far as I am aware. Is your computer running 24 / 7 at home when you are away from home?
