ZHA 3/4 bindings stopped working and now unable to re-bind

Looks as if it is a widespread issue with a Tradfri firmware update.

After OTA update Ikea E1524/E1810 can't be bound to group - how to downgrade?

problem

## What happened 1. I upgraded Ikea E1524/E1810 remote to the latest version using Zigbee2mqtt — 2.3.075 2. Deleted remote and readded it back (this was not related to OTA update so not sure how important is it to reproduce the issue) 3. Tried to setup the binding between the remote and light group as I previously had. It doesn't work I read about the same issue in ZHA related issue: https://github.com/home-assistant/core/issues/43969#issuecomment-854951280. So looks like the problem is reproducable. ## What did you expect to happen Is there any way to downgrade the firmware? I have bunch of E1524/E1810 remotes that are on 2.3.014 firmware and they are working great. ## How to reproduce it (minimal and precise) ## Debug info Zigbee2MQTT version: 1.19.1 Adapter hardware: CC2652 Adapter firmware version:
