check address says
Yes! This is a valid Standard XMR address. (in green txt)
maybe I'll wait a week and try to add the address again i guess.

at first in my wallet app next to receive I was using the primary address listed as #0 and the first number was a 4.

but eventually i decided to click the little plus next to "create new address" and i named it test so it reads as #1test and does begin with an 8.

to be clear I now have a #0 primary that starts with 4 and #1 test that starts with 8. however both give me the same error result on the pool's monero wallet page "Failed to update your account: Invalid coin address" when i try to add either

earlier today i made a post in the help section
https://bitcointalk.org/index.php?topic=5206319.0

but someone suggested Id have better luck here.

I upgraded my wallet to 0.15.0.1 on the 30th.  But I don't know if the upgrade was supposed to give me a new receiving addy because i still have the same one and it no longer seems to be working on miningpoolhub.com. I can no longer add the characters I receive from my wallet's primary addy under receive.

the pool has this posted
but i dont know what they are asking for

Id like to withdraw the xmr from my acc but im not sure what miningpoolhub wants me to copy paste into the payment address box because the line of characters the wallet provides, which is the same as before i upgraded btw,  generates the "Failed to update your account: Invalid coin address" when i try an add it.

any advice, suggestions to try would be greatly appreciated
TIA

I don't think I ever used a payment id before. I had clipboard/pasted the receiving address that is a long string of characters provided from the wallet. Do you know if or what new info they are asking me me to paste in the payment address box or "payout to" box?

right now on miningpoolhub.com my "payment address" box and my "payout to" boxes both have my receiving address in them. should they now look different from each other after the wallet update? what new info is the miningpoolhub asking me for from my wallet in order to begin to receive transactions again to the new upgraded wallet  IYO?

I feel like I'm not supplying the pool with the proper info they want based on that quote because i havent received payment to the upgraded wallet 0.15.0.1 by trying to cash out

 but i dont know what exactly they are asking me to copy/paste differently than from the receiving address that was working before

I'm not sure what that means? I've been mining xmr for just a few months with only two cards and a cpu. so im kinda of a noob.

On the 30th when xmr started using randomX I upgraded my monero wallet to v.0.15.0.1

on miningpoolhub, the pool I use they posted

what does insert address with dot mean? I cant figure out how to insert my receiving address properly or exactly what it is they're asking for 

In my updated monero wallet v.0.15.0.1 the receiving address is the same string of characters as it was in the old version. 

I feel like miningpoolhub is asking me to paste a new receiving address or payment address but I don't know what i should be trying to copy/paste.

Id really like to withdrawal the coin I've mined over the past two weeks but iI am stuck.

thanks for reading this
any advice, suggestions or urls to read that would help get my withdrawals working again would be greatly appreciated
