I faced a similar issue after upgrading to /e/OS 2.6.3 (a13 → a14). In the discussion thread for that /e/OS version another user described it like this: Feedback for v2.6.3 - #214 by rikshaw
And proposed the following workaround, which solved the issue for me: Feedback for v2.6.3 - #263 by rikshaw
Cheers!
