Regarding 1st issue, recently many are facing it and for reference can see this post where I tried to compiled related recent reports: No user profile or actor images displaying, but only on the Fire Stick - #3 by Mrs403
For 2nd issue, just to make sure you have your libraries pinned on homescreen? If not, then it won’t show.
If your libraries are pinned but still Continue Watching is missing then providing info asked by BigWheel will help in identifying issue.
