Absolutely, as a Linux uswr if only 18 months it was a complete balls up me trying to install Signal from tje shitty instructions. Their website, a seasoned Linux user in the forum said how he could see how I was confused becase the command lines on the Singnal website to do the install all ran together, since then it’s been fine but just Flatpak FFS.
