Can't complete main story mission Sieze the day, control the future and more.....

I'm playing on the Ps4 and every single time I try to start the cronkhite bunker part of sieze the day, control the future I get stuck in a never ending loading screen. I've restarted the mission several times, swapped servers, abandoned the mission and drove back to Headlands Transit instead of fast traveling and I've also watched all cutscenes but still I get stuck in a never ending loading screen.

My second issue is with the side mission called Lost in transit, the item I am supposed to be grabbing for the mission never spawns making the mission impossible to complete.

My third and biggest issue is with the exploring marin II pursuit. I completed all of the side missions Saturday but after the hot fix on Sunday, it says that they are not complete and yet there is no way to redo them and they are not on my map at all when I pull it up.

Please fix these.

I am in the same situation on the main quest. Mission is "A Bullet For A Badman" and when trying to enter Dogtown Mine, I get an infinite loading screen, after some time, I get matchmaking failed and to restart. I have closed app and stuff, but still get the same thing. This keeps me from progressing since yesterday.
