There seems to be generic internet issues. At first only the eWeLink connection seemed to be affected, but I’ve now seen that also Facebook, Twitter and Telegram are very slow loading
So far you might see the following effects on the eWeLink app:
toad messages “Failed. Network error.”
no scenes displayed
no response of some (mainly non-LAN mode) devices
The best thing you can do is report the issue with the in-app feedback at: Profile > Help & feedback > Feedback > document icon at the upper right corner.
