Used to have no problem connecting from my iphone to remote control my MacOS Mojave. I had to blow away my MacOS keychain files and start over. Since then I am unable to connect. When I try to initiate connection from BTT Remote from my iphone 8+ it immediately brings up a BTT dialog box on my Mac saying "Encryption Information: For some reason BTT was not able to retrieve the information it needs to secure the connection to the BetterTouchTool Remote from your Keychain. [OK]"
Running BTT 3.374 on MacOS Mojave
