What is your Account ID, please? (In plain text: There is a copy-to-clipboard function on the My Account page, please paste the result in reply).
Next: We have indications that some component(s) of ActionTiles may be suddenly blocked by ad blockers or other similar firewall. Please disable ad blocker to confirm, including such devices as PiHole if you are running one.
You can also test ActionTiles outside your regular home network such as on a cell phone 4G, or at an internet cafe / hotspot.
We are using Google's Firebase services which have suddenly been added to one or more ad-block "blacklists".
Since we have no control of these blacklists (nor the specific Firebase servers or IP addresses used by ActionTiles), we can only recommend using your logs to whitelist anything that ActionTiles appears to access.
