Confluence ONLYOFFICE integration app plugin v.4.1.0 doesn't enable on Confluence 8.0.2

Hi!
I catch an error ‘This app failed to enable. Refer to the logs for more information’ when trying to enable ‘Confluence ONLYOFFICE integration app’.

It happend after upgrading Confluence v.7.11 to v.8.0.2 (and the plugin v.3.0.1 to v.4.1.0).

How to enable it?

These doesn’t help:

  1. Restarting Confluence
  2. Clearing plugins cache by removing folders (/plugins-temp, plugins-osgi-cache, plugins-cache)
  3. Removing/installing the plugin

If it happens because of unsupported Confluence v.8.0.2 by the plugin then when will be roll up a newest version of the plugin which will be support Confluence 8.0.2?

Hello @Aleksandr.K

Unfortunately, right now we do not have connector plugin for the version 8.0.2 of Confluence. We are working hard on it but, unfortunately, we do not have estimated date of the release of new version of connector plugin.
The connector plugin version 4.1.0 works with versions from 6.13.1 to 7.19.4.

Sorry for the inconvenience caused.
