Zapstore (npub10r8…t2p8) 0.1.5 does not work anymore for me. Cannot install or update any apps. I grant the right to install, see the download bar, then verifying package, requesting install. The system popup to confirm the installation appears. I acknowledge it, but it just disappears and Zapstore displays a red error in the install/update button.
