The ultimate mom dad or grandma distro is Linux Mint, might be worth trying it out to see if it has the same issue or not.
I was considering installing Mint for her, but decided against it because of the recent unverified flatpak controversy (she unfortunately still uses chrome, and would rather have her distro manage all her updates for her); but I think I might install Mint on an external hard drive just to quickly see if any of her issues persist.
