This. The answer is 100% this. Keep doing your soloing, but whenever you need to do group content(trial/dungeon/etc) try to do it with a group of friends. With people who know what theyre doing and can explain for you no dungeon should really take more then 20-25 mins, and the easy/story mode for trials should never run as long as 10 mins in the same scenario. The only exceptions to this are the 2 dungeons that end the ARR story. They can still be run in 20 mins each(or less), but it requires cutscene skipping to do that quickly as those 2 dungeons(castrum and praetorium) include multiple mid-run cutscenes rather then just the typical start-boss-pose ones. So for those 2 dungeons, your options will be skip cutscenes(you can rewatch them later from your inn room) or schedule these playthroughs in advance when you know you shouldnt have RL issues to interfere(youll also want to use party finder/friends rather then duty finder to make sure the team plays along with letting you see the cutscenes).
Best of luck!
