Changes in regulations 01/04/2022 Annex to the comprehensive Prosument Komfort p

Hello, I have a few questions. I am writing because there is no clear and clear answer anywhere, it is also hard to find out in Tauron, each consultant says something different.
At the beginning of February Tauron replaced the meter in connection with the notification of the construction of a micro-installation. Within a few days, my current tariff agreement with the seller's tariff was changed to the ''Prosument Komfort Plus'' option mentioned in the subject.
Then I got from Tauron distribution:
- Confirmation of connection to the micro-installation network.
Currently, in the inbox I found Anaks No. 1 to the Electricity Sale Agreement along with the distribution service, which regulates (in short):
- the rules of settling with the seller as the obligated seller,
- rules for the implementation of the distribution service in the field of receiving energy introduced into the network
- rights and obligations of the client
- rules for commercial balancing of energy generated by the customer provided by the seller.
It makes me wonder that the method of settlement is formulated in the annex?, especially since the first page of the LETTER concerns the instruction on withdrawal from the annex?
And here are the questions:
1. If I do not accept the annex, will I not be billed as a prosumer?
2. Is this a standard approach? The more so that in the annex and in fact in the GTC constituting an annex to the annex there are vague and puzzling clauses about which there were on portals and websites for posting videos.
3. Is an Annex required at all if I have an active contract?
While I understand the statement about the 12-month settlement period, the Annex really puzzles me.
I created this topic to clarify the following issue:
Is it possible, in the current (already known form) of the new regulations of the RES Act, for the Seller to those who introduced electricity generated by the micro-installation to the grid by March 31, 2022 to change the current method of settling the energy introduced after April 1, 2022?
I will be grateful for help in understanding, attached is a letter marked as "transition to prosumer settlement", instruction and GTC
