It would only work if Kodi (addons) had write permission access to wherever estuary is. Which I guess it must if updates are downloaded...anyhoo, will give it a try soon.
Addons I wrote &/or maintain:
OzWeather (Australian BOM weather) | Check Previous Episode | Playback Resumer | Unpause Jumpback | XSqueezeDisplay | (Legacy - XSqueeze & XZen)
Sorry, no help w/out a *full debug log*.
