I see this message:
You are running Home Assistant 2021.2.3, to update to this version of the add-on you need at least version 2021.2.0b0 of Home Assistant
So, the 2021.2.0b0 is higher than 2021.2.3???

I ran in to this as well.
However I think it is known.
And explanation is in this bug report.
Gotcha, thankyou for the hint!
