Apps should work longer even without net connection

I have been Adobe customer for over 30 years. The shift from bought app packages to online apps has had both good and bad effects, but what's most important, the apps & fonts should work without net connection for a much longer time. Sometimes there are problems with net connections in either end. But since I continually pay for the use of the apps and need them for actual work which has schedules, I want to be sure the apps work even through the connection breaks. Or then I should be able to bill Adobe for the lost work time.
