Before all this it was just seconds. Now browsing tones is a slog. But hey it's working at least now which means someone is working on it somewhere

Delete the ToneNET cache for the app being used (AmpliTube 5 and/or TONEX).
To do this, go to the Documents folder, then go to the IK Multimedia folder to find either the TONEX or AmpliTube 5 folder. Enter this folder and find the ToneNET folder. Delete it's contents, leaving the folder there, but empty.
