The original post was approved withing a few hours of you posting. Nothing is stuck or needs approving. Just nobody cared to reply to your post. I'd guess because nobody can replicate the claimed problem. For example: I'm running LE13 nightlies on an RPi5 and the InfoWall view is available everywhere for me. Right now LE13 is still using the same Kodi Omega version as LE12 as we didn't bump up to Kodi 'P' just yet.
I would stop and rename the /storage/.kodi folder to /storage/.kodi-old and restart. If the (now empty, all new) Kodi library DB has Infowall back, something is messed up or corrupt in the kodi-old settings or DB files and you can now stop, move files, restart Kodi to move old config and bits to the 'new' Kodi folder until you find out what caused the issue.
You can also share a debug log, but I rather doubt the issue will be visible that way.
