[Tails-testers] Tails 4.22~rc1 question

Hi there,

First off, the custom bridges that I had generated from
bridges.torproject.org work fine after adjusting the clock on the 4.22~rc1
as opposed to the 4.21.

Second, it says on the site that beta versions should be used only for
testing and is unsafe to use. I did not notice that statement and now I am
left with the beta on my flash drive. Is there any way to downgrade within
the flash drive?

Thank you for your great work, the Tails Team.
