@yaniiliev No dear developer, you made an ecosystem using free features that made it unusable in the free version so people should buy the paid version.
Few issues I noticed, I think this was all well planned –
1) you made the separate plugin as file import (i have faced this on few sites)
2) you have now disabled the file import limit constant earlier it was able to import files up to 512MB without touching server max import/upload size. You also have disabled the backup feature because with that we were able to upload the file from cpanel as now server allows only small files upload. My host refuses to change setting for me. The only option is to buy the addon. So this is now a useless plugin for me.
I will rather buy a paid plugin of other developers but not this anymore.
