Welcome back to the Community, @Verwijs!
We appreciate your feedback on this.
Please note that the Dropbox app’s cache gets automatically erased every 3 days, so that syncing may not be affected.
Can you please let me know why you believe this feature would be of help in your case, and what you mean when saying that you’d like to have a reset button, when the Dropbox app has connection issues? Any further examples you can provide would be appreciated.
Give me a nudge when you have more updates.
