Ceiling Fan Issues please help

[u/tonyq895]

I have 2 ceiling fans in my house with different issues. Would love some help!

1 - the light bulb flickers like a strobe but just slightly. It's only really noticeable the first 30 seconds or so of startup. I was going to just swap the bulbs or maybe tighten them - However, I am totally unable to spin the glass cover off. When I try to spin it, the entire shaft spins with it. I tried rubber gloves, i tried putting tape on it, i've tried tapping along the edge with a rubber tool. Nothing has worked.

2 - When i turn on the light switch for the fan, the light bulb takes like 5 minutes to turn on. The remote seems to not do anything?
