Is there any relationship between copay and Bitpay wallet?
Yes, AFAIK bitpay backs the development of copay wallet.
I've been using copay for some years and I noticed that it's not supported anymore, it's like the team drop any future development on this bitcoin wallet or even abandoned it, any info will be appreciated thanks
I check their
github issue page which has lots of complains, lost coins and etc.
I also check the one in playstore but I guess its fake as I
see its different the one listed on
cryptoslate directory with less numbers of downloads. I didn't see any updates from their official source regarding this as well. Though their windows and mac version is updated 15 days ago.
While things aren't good I suggest you to dont update your copay especially if you're using android as there are reports of lost coins.
Or move your funds to better wallet where you can fully control your wallet like electrum (
