No one will click on links here due to risk. It does sound like you need to reset your toilet. Either call a plumber or watch a YouTube video and do it yourself.

It will need a new wax ring, but there could be other issues also in play. The drain line could be partially blocked and/or the mounting flange could be broken. The floor under the toilet could be deteriorated, thus the toilet rocks, causing the wax ring to fail.

Removing the toilet to replace the wax ring will give you the opportunity to check the overall situation.

The toilet in my son's house wobbled a little. Luckily he called a plumber - the flange was cracked, and fixing it was far above his DIY skill level.

I'm unable to see beneath toilet from this distance therefore can't tell what's wrong.

I would think you need a flange extension added to bring the flange level with or slightly higher than the newer tiled floor atop the previous still existing flooring. Ask a plumbing store if a thicker wax ring with the plastic horn extension might work but ideally the flange needs to be correct height.
