Bugs: (1)Multi-camera angle becomes all black and (2) audio not playing at all (Fix)

I've come across 2 errors and also submitted the bugs. The main purpose of this is to show other people who have these bugs how to fix them and also hoping someone from Adobe spots this. I made a video in hopes of making it easier to understand for both regular users and Adobe staff to hopefully fix asap.

Bug #1:

Audio doesn't play in composition.

Fix: Go into one of the compositions and solo any track, this should now fix it.

Video: Adobe Premiere error - automatically muted audio (fix) - YouTube

Bug #2:

One of your angles in the multi-camera footage goes black all of a sudden

Fix: Go into the source file that has all the multicamera angles, then open in timeline. Move the layer that's being blacked out then move it back (or click undo). This should now fix it

Adobe please fix these! It's a huge problem, especially for people who have to upload to youtube or deliver to clients and things suddenly start breaking.
